Hi .. @Rajesh , @Jay SenSharma .. thanks for getting back on this as quickly as you guys did. And apologies for late response as restoring business continuity and back log processing took a while. We did not update any packages or any core component of HDP suite. The following package check return the same component versions in all nodes. [dataops@dh07 ~]$ rpm -qa | grep ambari ambari-metrics-hadoop-sink-2.2.1.0-161.x86_64 ambari-agent-2.2.1.0-161.x86_64 ambari-metrics-monitor-2.2.1.0-161.x86_64 [dataops@dh08 ~]$ rpm -qa | grep ambari ambari-metrics-collector-2.2.1.0-161.x86_64 ambari-metrics-monitor-2.2.1.0-161.x86_64 ambari-agent-2.2.1.0-161.x86_64 ambari-metrics-hadoop-sink-2.2.1.0-161.x86_64 [dataops@dh01 ~]$ rpm -qa | grep ambari ambari-metrics-monitor-2.2.1.0-161.x86_64 ambari-server-2.2.1.0-161.x86_64 ambari-agent-2.2.1.0-161.x86_64 ambari-metrics-hadoop-sink-2.2.1.0-161.x86_64 Even now with all processes running fine we have the HDFS Service Check issue, but now the Service check errors out in DH01 (stand by NN). PS : By the way , we had to take out DH04 and DH03 out of the cluster to restore sanity , we were able to stabilize the cluster then onwards. We are working to re balance the HDFS and then reformat DH04 to bring it back as a fresh Data nodes.

An update to this post for practitioners who land here to solve similar problems: We added a new node to the cluster by Ambari GUI (using FQDN during install). We could see the node in the HOSTS list in AMBARI and RESOURCE MANAGER UI, but it was not accepting containers. Also we could not see the new node in the -> Datanode Tab of name node view (http://<Active Name Node Host FQDN>:50070/dfshealth.html#tab-overview) Executed this : hadoop dfsadmin -refreshNodes Followed by this : hadoop dfsadmin -report But could not see the new node in the report We looked at the Datanode error log: 2017-09-01 15:25:59,859 INFO datanode.DataNode (BPServiceActor.java:register(768)) - Block pool BP-1930018148-58.162.144.211-1462411884867 (Datanode Uuid 734af6ba-e5a0-4f6e-81d4-7ad089f6d685) service to dh02.int.belong.com.au/XX.XXX.XXX.XXX:8020 beginning handshake with NN2017-09-01 15:25:59,864 ERROR datanode.DataNode (BPServiceActor.java:run(828)) - *Initialization failed for Block pool BP-1930018148-58.162.144.211-1462411884867 (Datanode Uuid 734af6ba-e5a0-4f6e-81d4-7ad089f6d685) service to dh02.int.belong.com.au/XX.XXX.XXX.XXX:8020 Datanode denied communication with namenode because hostname cannot be resolved (ip=YY.YYY.YYY.YY, hostname=YY.YYY.YYY.YY)*: DatanodeRegistration(0.0.0.0:50010, datanodeUuid=734af6ba-e5a0-4f6e-81d4-7ad089f6d685, infoPort=50075, infoSecurePort=0, ipcPort=8010, storageInfo=lv=-56;cid=CID-0019b609-89c6-421f-b98b-21607b8a21c6;nsid=1515412344;c=0) at org.apache.hadoop.hdfs.server.blockmanagement.DatanodeManager.registerDatanode(DatanodeManager.java:883) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.registerDatanode(FSNamesystem.java:4541) at org.apache.hadoop.hdfs.server.namenode.NameNodeRpcServer.registerDatanode(NameNodeRpcServer.java:1350) at org.apache.hadoop.hdfs.protocolPB.DatanodeProtocolServerSideTranslatorPB.registerDatanode(DatanodeProtocolServerSideTranslatorPB.java:96) at org.apache.hadoop.hdfs.protocol.proto.DatanodeProtocolProtos$DatanodeProtocolService$2.callBlockingMethod(DatanodeProtocolProtos.java:29062) at org.apache.hadoop.ipc.ProtobufRpcEngine$Server$ProtoBufRpcInvoker.call(ProtobufRpcEngine.java:616) at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:969) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:2151) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:2147) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:422) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1657) at org.apache.hadoop.ipc.Server$Handler.run(Server.java:2145) and realized that Datanode denied communication with namenode because hostname cannot be resolved In the new node , execute the following to verify the IP hostname -f We added the following line in the /etc/hosts file of Active & Secondary Name node . YY.YYY.YYY.YY dh10.int.belong.com.au dh10 Restarted Datanode and Node Manager Restarted Datanode and Node Manager on the new node. On refreshing Namenode dashboard i could see the new node listed. (Note - We did not have entries for other datanode in the /etc/hosts file,hence we realized that what we did was to just work around the problem) I discussed this issue with Server Admin to check the DNS resolution of the new box , as our cluster used a DNS resolver rather than /etc/hosts for DNS/hostname resolution . The check did not seem to be an issue. Then we analysed the DataNode log again to see that the error indicated new node's hostname as an IP address : (ip=YY.YYY.YYY.YY, hostname=YY.YYY.YYY.YY) This then became a reverse DNS lookup problem, Server Admin cross checked this in the DNS Server to find that reverse DNS was not set up for the new data node. Once the settings were updated , i went ahead and removed the entry in the /etc/hosts files in the Active & Secondary Name node , restarted datanode and nodemanager in the new node. It has all worked out fine since then.

Hi ALL, Environment: Cluster details: (All are on internal Datacentre and all nodes are VM servers) DH01 - Active Name Node DH02 - Secondary Name Node Data Nodes -DH03,DH04,DH05,DH07,DH08,DH09 We had a disk failure in DH03 yesterday (it shared a partition with all other datanodes) and since then we have had cluster issues. We were able to restore functioning of the cluster by restarting services and servers itself by end of the day. But today we have an issue with DH04 one of the datanodes , There is no error in the Ambari Dashboard for this node.

@Jay SenSharma Thanks for getting back on this, the details of Ambari Agent as below ]$ ambari-agent --version 2.2.1.0 ]$ rpm -qa|grep ambari-agent ambari-agent-2.2.1.0-161.x86_64 Its does seem like , the issue indicated in the Jira is relevant to the issue that occurred. As of now this issue has occurred only once but it does seem like migrating would be a good option to avoid this issue in future. Also, i had indicated that Namenode CPU WIO was N/A, after a few hours i am able to see the metric on the Dashboard.

The issue started with an Alert on Hive Metastore Service: Metastore on dh01.int.belong.com.au failed (Traceback (most recent call last): File "/var/lib/ambari-agent/cache/common-services/HIVE/0.12.0.2.0/package/alerts/alert_hive_metastore.py", line 183, in execute timeout=int(check_command_timeout) ) File "/usr/lib/python2.6/site-packages/resource_management/core/base.py", line 154, in __init__ self.env.run() File "/usr/lib/python2.6/site-packages/resource_management/core/environment.py", line 158, in run self.run_action(resource, action) File "/usr/lib/python2.6/site-packages/resource_management/core/environment.py", line 121, in run_action provider_action() File "/usr/lib/python2.6/site-packages/resource_management/core/providers/system.py", line 238, in action_run tries=self.resource.tries, try_sleep=self.resource.try_sleep) File "/usr/lib/python2.6/site-packages/resource_management/core/shell.py", line 70, in inner result = function(command, **kwargs) File "/usr/lib/python2.6/site-packages/resource_management/core/shell.py", line 92, in checked_call tries=tries, try_sleep=try_sleep) File "/usr/lib/python2.6/site-packages/resource_management/core/shell.py", line 140, in _call_wrapper result = _call(command, **kwargs_copy) File "/usr/lib/python2.6/site-packages/resource_management/core/shell.py", line 291, in _call raise Fail(err_msg) Fail: Execution of 'export HIVE_CONF_DIR='/usr/hdp/current/hive-metastore/conf/conf.server' ; hive --hiveconf hive.metastore.uris=thrift://dh01.int.belong.com.au:9083 --hiveconf hive.metastore.client.connect.retry.delay=1 --hiveconf hive.metastore.failure.retries=1 --hiveconf hive.metastore.connect.retries=1 --hiveconf hive.metastore.client.socket.timeout=14 --hiveconf hive.execution.engine=mr -e 'show databases;'' returned 5.

Then, i looked at memory utilization which indicated that SWAP has run out. ]$ free -m total used free shared buffers cached Mem : 64560 63952 607 0 77 565 -/+ buffers/cache: 63309 1251 Swap : 1023 1023 0 I tried to restart Hive Metastore service from Ambari but that operation Hung for over 30 minutes without printing anything in the stdout and strerror logs. At this point I involved Server Administrator in the investigation and it was revealed that the following process had reserved upto 40 GB. It seemed strange (I am not sure what is the optimal utilization pattern for Ambari Agent/Monitor ?? !! ) root 3424 3404 14 2016 ? 52-22:05:00 /usr/bin/python2 /usr/lib/python2.6/site-packages/ambari_agent/main.py start At this point i tried to restart Ambari Metric service on the name node from Ambari, the operation Timed out and then "Heart Beat" from the node stopped. As can be seen in the image. I was not able to restart Ambari Metric service on the Name Node from Ambari Console, as the option was disabled. I tried to so a rolling restart of all Ambari Monitor Services, but the Monitor Service on Name Node did not start. At this point we decided to 2 things, add more swap space (Admin added 1 more GB ) and then i stopped and started Ambari Services as follows: #Stop operation did not succed at first go and i had to kill the Pid sudo su - ams -c '/usr/sbin/ambari-metrics-monitor --config /etc/ambari-metrics-monitor/conf stop' sudo su - ams -c '/usr/sbin/ambari-metrics-monitor --config /etc/ambari-metrics-monitor/conf start' #I looked at Agent Status sudo ambari-agent status#The agent was not running, Hence i started the agent sudo ambari-agent start After the agent start the monitor from this node was up and reflected in Ambari. The only issue that i have now is that Namenode CPU WIO is N/A on the Ambari Dashboard ? , Will be helpfull to know how to get this back ? Also, what i intend to do is to review HiveServer2 and Metastore heap sizes which current stand at, again would these settings cause this issue were swap runs out. This has not happened before ! HiveServer2 Heap Size = 20480 MB Metastore Heap Size = 12288 MB Environment Information: Hadoop 2.7.1.2.4.0.0-169 hive-meta-store - 2.4.0.0-169 hive-server2 - 2.4.0.0-169 hive-webhcat - 2.4.0.0-169 Ambari 2.2.1.0RAM: 64 GB Helpfull links: https://community.hortonworks.com/questions/15862/how-can-i-start-my-ambari-heartbeat.html https://cwiki.apache.org/confluence/display/AMBARI/Metrics

HI @Priya Parmar , From some amount of research(Not deep dive) that i did during that time , i could not find a reference to what i wanted to achieve hence i abandoned the approach and did not use AVRO schema , as i had limited time at hand. Ref: https://cwiki.apache.org/confluence/display/Hive/AvroSerDe#AvroSerDe-Overview–WorkingwithAvrofromHive Do let me know if you got around this pattern or if a way forward has been developed.

suhel_khan · ‎07-21-2017

Hi All, This is a more capacity planning question. Over the last few months i have observed that YARN RAM utilization of our cluster has gone up considerably , due to new process being on boarded onto the cluster. At this point i am trying to find out the length of time (cumulative) through the day for which RAM usage is peaking. Any information on how to go about this will be helpfull. Currently: Hadoop2.7.1.2.4.0.0-169 Ambari - 2.2.1 HDP 2.4 Master - 2 (63 GB RAM) ,DN -6 (63 GB RAM) RAM 320 GB Total allocation.

suhel_khan · ‎07-21-2017

@mqureshi .. Thanks for getting back. I have reduced the HiveServer2 Heap Size to 20 GB and observing the behavior, i intend to reduce to 12 GB ,step wise over the coming days.

Hi @ssathish, I did look at the Link you posted and decided to delete the file. CAUTION: For some reason a few hours later there were inconsistencies in the cluster . One of the data nodes (D5) were clean up was done had corruption in the way containers were processed. Some jobs for which containers were lunched in D5 executed to completion successfully and some other jobs failed due to Vertex failed error. We could not find any errors in RM log/Datanode Log/Node Manager Log We had to remove D5 off the cluster and reinstall node manager to set things right.

Hi All, I noticed this today. The resource manager Node View shows that there is issue with DH07 log directories : 1/3 local-dirs are bad: /nfs/hadoop/yarn/local; 1/3 log-dirs are bad: /nfs/hadoop/yarn/log A look at the disk partitions give the below. There seems to be plenty of space in there [root@dh07 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00root 13G 854M 11G 8% / tmpfs 32G 16K 32G 1% /dev/shm /dev/sda1 485M 57M 403M 13% /boot /dev/mapper/VolGroup00-LogVol00tmp 1.2G 44M 1.1G 4% /tmp /dev/mapper/VolGroup00-LogVol00usr 30G 4.5G 24G 16% /usr /dev/mapper/VolGroup00-LogVol00var 151G 7.2G 136G 6% /var /dev/mapper/VolGroup00-LogVol00data 1004G 486G 468G 51% /data dh03:/ 78G 28G 47G 38% /nfs resourcemanagerview.png The Ambari Dashboard does not indicate any issues with DH07 and has the following ambaridashboard.png I am trying to understand if this is symptomatic of some other issue that i should be looking into.

@mqureshi The cluster currently only has one active name node. Is there a better way to find out the 'Active Node' ? I used the following as well.. but does not distinguish curl --user admin:admin http://dh01.int.belong.com.au:8080/api/v1/clusters/belong1/host_components?HostRoles/component_name=NAMENODE&metrics/dfs/FSNamesystem/HAState=active dh01 ~]$ curl --user admin:admin http://dh01.int.belong.com.au:8080/api/v1/clusters/belong1/host_components?HostRoles/component_name=NAMENODE&metrics/dfs/FSNamesystem/HAState=active [1] 16533 -bash: metrics/dfs/FSNamesystem/HAState=active: No such file or directory [ayguha@dh01 ~]$ { "href" : "http://dh01.int.belong.com.au:8080/api/v1/clusters/belong1/host_components?HostRoles/component_name=NAMENODE", "items" : [ { "href" : "http://dh01.int.belong.com.au:8080/api/v1/clusters/belong1/hosts/dh01.int.belong.com.au/host_components/NAMENODE", "HostRoles" : { "cluster_name" : "belong1", "component_name" : "NAMENODE", "host_name" : "dh01.int.belong.com.au" }, "host" : { "href" : "http://dh01.int.belong.com.au:8080/api/v1/clusters/belong1/hosts/dh01.int.belong.com.au" } }, { "href" : "http://dh01.int.belong.com.au:8080/api/v1/clusters/belong1/hosts/dh02.int.belong.com.au/host_components/NAMENODE", "HostRoles" : { "cluster_name" : "belong1", "component_name" : "NAMENODE", "host_name" : "dh02.int.belong.com.au" }, "host" : { "href" : "http://dh01.int.belong.com.au:8080/api/v1/clusters/belong1/hosts/dh02.int.belong.com.au" } } ] } Also hdfs-site.xml does not have the property dfs.namenode.rpc-address.

@mqureshi I used "-b" option to push the processing to background. I have also tried the following from server that has NN. Trial 1: (on Command Prompt) nohup sudo -u hdfs hdfs balancer -threshold 5 > /var/log/hadoop/hdfs/balancer.$(date +%F_%H-%M-%S.%N).log 2>&1 & Trial 2: (on Command Prompt) . DH05 needs to be offloaded as its the most unbalanced sudo -u hdfs -b hdfs balancer -threshold 5 -source DH05 > /var/log/hadoop/hdfs/balancer.$(date +%F_%H-%M-%S.%N).log 2>&1 & I get the same output from Balancer as it exists stating that "The cluster is balanced". It's somehow not able to get the current stats on data in the datanodes.

Hi All, Problem Statement: I have a source system that takes website data and sends out a lot of columns about 500+, At this point we only have interest in 100+ columns, we are trying to create a mechanism by which its easy to modify the HIVE table schema as the need to read more column arises. I have previously used AVRO schema files with JSON data and it worked quiet well to help add new columns easily to the schema file without altering data file. But currently the source system can only send flat CSV. I am trying to create a HIVE table and read this file as below CREATE EXTERNAL TABLE players ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' STORED AS TEXTFILE LOCATION 'hdfs://xxxxxcluster1/apps/hive/warehouse/test.db/players' tblproperties ('avro.schema.url'='hdfs://xxxxxcluster1/tmp/prototype/players.avsc',"skip.header.line.count"="1"); Error: (I have changed all file permissions to 777) FAILED: SemanticException [Error 10043]: Either list of columns or a custom serializer should be specified I have not been able to find references to reading TEXTFILE with avro schema. Is this possible to do ? or is there a better way to make schema update modular with TEXTFILE data rather than having to drop and recreate table every time.

Hi @Jay SenSharma, Thanks for your input. I removed the other repo files and have only "ambari.repo", "HDP.repo" and "HDP-UTILS.repo" and ran the following: sudo python /usr/lib/python2.6/site-packages/ambari_agent/HostCleanup.py --silent --skip=users yum clean all ls -ltr /etc/yum.repos.d/ But , i still could not get around the following error that was there previously: File "/usr/lib/python2.6/site-packages/resource_management/core/shell.py", line 291, in _call raise Fail(err_msg) resource_management.core.exceptions.Fail: Execution of '/usr/bin/yum -d 0 -e 0 -y install ambari-metrics-monitor' returned 1.

I have 6 AWS Ec2-Instances (3 Masters / 3 Slaves). 1 has Public IP (My Main Server) and 5 have EIP. (I added EIPs on other servers in order to try and resolve the issue, assuming that some of the libraries might need to be downloaded from net.) All AWS-EC2 instances are same Instance type-c3.xlarge Availability zone-ap-southeast-2a AMI ID -RHEL-6.5_GA-20140929-x86_64-11-Hourly2-GP2 (ami-eb2a47d1) I downloaded repos onto my Main Sever , changed the BASE URL for ambari.repo and HDP.repo and then pushed these to other servers. I updated the same local URL details in the AMBARI UI -> CLUSTER INSTALL WIZARD. Issue came up when i tried to install Metrics Collector and Zookeeper on to the EC2 nodes.

Several Extracts Job in Datameer (Rapid ETL/BI tool, sits on top of hadoop) are reading data out of salesforce objects. The largest extract is 1.4 GB(Task object) and the smallest extract is 96 MB(account object). Datameer uses REST API Based connector , a SOQL query is supplied to the connector and records are fetched accordingly (https://documentation.datameer.com/documentation/display/DAS60/Salesforce). Datameer compiles the job and hands over the execution to the execution framework (Tez) All the saleforce extract jobs run with 1 Map tasks. But, There are other extract jobs in datameer that read data from flat files(50 - 200 MB) on a sftp server and use between 3-5 map tasks. About SOQL: https://developer.salesforce.com/docs/atlas.en-us.soql_sosl.meta/soql_sosl/sforce_api_calls_soql_changing_batch_size.htm SOQL pulls a max of 2000 records per batch My question : Considering that data from flat file is running with multiple map tasks, does the issue corresponds to SOQL batch size which only pulls 2000 records per request hence resulting in allocation of only 1 mapper. How does MR program determine total size of the input extract when dealing with source like salesforce or for that matter even a database. Environment Information: Hortonwork 2.7.1 Cores Per Data node=8 RAM per Data node=64GB No of datanodes = 6 Block Size : 128 MB Input Split info: mapreduce.input.fileinputformat.split.maxsize=5368709120 (5 GB) mapreduce.input.fileinputformat.split.minsize=16777216 (16 MB) Execution Framework: Tez Memory Sizes: <property> <name>mapreduce.map.memory.mb</name> <value>1536</value> </property><property> <name>mapreduce.reduce.memory.mb</name> <value>2048</value> </property><property> <name>mapreduce.map.java.opts</name> <value>-Xmx1228m</value> </property><property> <name>mapreduce.reduce.java.opts</name> <value>-Xmx1638m</value> </property> <property> <name>yarn.app.mapreduce.am.resource.mb</name> <value>1024</value> </property><property> <name>yarn.app.mapreduce.am.command-opts</name> <value>-Xmx819m -Dhdp.version=${hdp.version}</value> </property> Compression is enabled: <property> <name>io.compression.codecs</name> <value>org.apache.hadoop.io.compress.GzipCodec,org.apache.hadoop.io.compress.DefaultCodec,org.apache.hadoop.io.compress.SnappyCodec</value> </property> mapreduce.output.fileoutputformat.compress=true mapreduce.output.fileoutputformat.compress.type=BLOCK mapreduce.map.output.compress=true mapred.map.output.compression.type=BLOCK
