@Robert Levas : Thanks a lot for the solution, 'unsupported type' issue has been resolved after kerberose config changes. I have raised another issue for storm spenago load balancer related here.

@Akhil S Naik : Thanks for the reply. Yes it was indeed table not found. But could not find how the table came missing as it was running perfect before enabling kerberose. Just creating the table in hbase solved the issue. I have to create metron_update,profiler,user_settings tables in hbase.

I have setup a HCP 1.6.0 cluster using ambari 2.6.2.2. After enabling kerberose in my cluster via Ambari UI referring this link. All my services starts fine except metron. I am getting following errors in metron-indexing service. 2018-08-13 14:15:53,017 - Setting Indexing ACL configured to True 2018-08-13 14:15:53,017 - File['/usr/hcp/1.6.0.0-7/metron/config/zookeeper/../metron_indexing_acl_configured'] {'owner': 'metron', 'content': 'This file created on: 2018-08-13 14:15:53', 'mode': 0755} 2018-08-13 14:15:53,018 - Writing File['/usr/hcp/1.6.0.0-7/metron/config/zookeeper/../metron_indexing_acl_configured'] because it doesn't exist 2018-08-13 14:15:53,018 - Changing owner for /usr/hcp/1.6.0.0-7/metron/config/zookeeper/../metron_indexing_acl_configured from 0 to metron 2018-08-13 14:15:53,018 - Changing permission for /usr/hcp/1.6.0.0-7/metron/config/zookeeper/../metron_indexing_acl_configured from 644 to 755 2018-08-13 14:15:53,018 - Setting HBase ACLs for indexing 2018-08-13 14:15:53,018 - kinit command: /usr/bin/kinit -kt /etc/security/keytabs/hbase.headless.keytab hbase-sdssystembed@MYCOMPANY.COM; as user: hbase 2018-08-13 14:15:53,018 - Execute['/usr/bin/kinit -kt /etc/security/keytabs/hbase.headless.keytab hbase-sdssystembed@MYCOMPANY.COM; '] {'user': 'hbase'} 2018-08-13 14:15:53,060 - Execute['echo "grant 'metron', 'RW', 'metron_update'" | hbase shell -n'] {'logoutput': False, 'path': ['/usr/sbin:/sbin:/usr/local/bin:/bin:/usr/bin'], 'tries': 3, 'user': 'hbase', 'try_sleep': 5} 2018-08-13 14:15:58,726 - Retrying after 5 seconds.

@Lija Mohan, Seems this is metron maven build related issue in windows platofrm. This is due to metron-config & metron-alerts UI module npm build issue. Could you try commenting out those under metron-interface module's pom as a work around ? Hope you don't need UI projects built in your local for this. I will post here If I found a tweak or fix for the UI module builds.

Metron's latest version (0.5.0) supports custom parsers deployment as plugin as per this reference. When can we expect HCP release which supports latest metron ? This will make custom parser deployment much easier.

Unfortunately I terminated a slave instance in my hcp cluster which was hosting hive server 2, hive metastore and mysql db. In my ambari UI I am getting heart beat lost issue in the services which were in that instance. To fix this I tried adding new host to bring back my services using Host - > Add new Host. I followed below steps for this.
1 - Create new EC2 instance - Cent os 7 - Same as my other instances.
2- Installed yum update & epel repo adding
3- Setup password less authentication from Ambari server to the new Host
4- Filled step 1 parameters - Private key and host ip for the new instance
After step 4 ambari UI is stuck ( Screen catpure - suck.png) and not going to futher step. I checked both ambari-agent & ambari server log but couldn't find any issues. What could be the reason for this ? How can I resolve or futher investigate ?

I have ambari managed 10 node hdp cluster ( 2.5.3.0 ). I am trying to index my netflow log ( 1 million records ) file using csv parser. Since my cluster nodes are lesser RAM 8 GB, I have controlled indexing traffic using spout.maxUncommittedOffsets - 100000 & topology_max_spout_pending - 100 to avoid resource contention in my storm workers. My storm configurations :
Number of kafka partition :5 Number of workers : 5
Storm supervisors : 5
Number of executors : 5
When I try to indexing netflow log file using metron sensor ( CSV parser ) It hangs when it reaches around .5 million. If I reduce the maxUncommittedOffsets to 10000 hanging comes near to 50k. So it seems it is depending on the maxuncommittedoffsets. Each time this issue happens if I delete kafka topics and restart storm and metron things will start work again and hangs if it reaches the same level. When I monitor the enrichment & indexing input topics using kafka consumer messages stop coming to main sensor input topic.
I have disabled both solr & elastic indexing using indexing configuration in metron UI. Could this be effecting offsetcommit ?
What happens in storm topology if messages reaches spout.maxUncommittedOffsets ? Does this check the committed value from zookeeper ? I had tried lot of times and when this issue comes I see the below log entry in my worker log continuously could this be the problem ? topic-partition [netflow-1] has unexpected offset [1118]. Current committed Offset [400359] Indexing config : {

I have an ambari cluster with 10 nodes as in the standard deployment architecture documentation with each node having 8 GB of memory. Smaller files indexing works fine and when I tried with large files .1 million records ( CSV file with csv parser / json with grok ) Indexing stops after writing around 90k records. Some issue with kafka indexing topology. How can I properly debug the issue ? I could not find any errors in storm UI except few warnings. I tried looking at the worker log file of storm where I could see below log, Whic I suppose causing the issue. 2018-04-24 06:13:36.787 o.a.s.k.s.i.OffsetManager Thread-17-kafkaSpout-executor[9 9] [WARN] topic-partition [newindexing-0] has unexpected offset [393].

Where can I find more details in logs ? I got the id of the topology from storm UI and looked under worker artifacts where the storm topology is running. I also checked the storm supervisor logs where I could see below log lines.

I am trying to add one node to my ambari cluster using blue print API which is created using ambari UI. I created blue print and try to add the node to the host group using ambari blue print REST API as below. curl -i -H "X-Requested-By: ambari" -u admin:pswd -X POST -d @new-host.json <serverurl>:8080/api/v1/clusters/hdpCluster/hosts/<host-id> I get the below error for this curl request. {
"status" : 400,
"message" : "Topology validation failed: org.apache.ambari.server.topology.InvalidTopologyException: Unable to retrieve cluster topology for cluster. This is most likely a result of trying to scale a cluster via the API which was created using the Ambari UI. At this time only clusters created via the API using a blueprint can be scaled with this API. If the cluster was originally created via the API as described above, please file a Jira for this matter."
}
Is it not possible to add node to cluster created using ambari UI ? Is there any other way for the same ?

I figured out the root cause and it solved my issue. Root cause was the 5th point in this link. Seems after I bring down EBS volume available space I had to decrease the 'Reserved space for HDFS' in ambari hdfs service advanced configuration. This is the dfs.datanode.du.reserved property. This was higher than the available space. Once I brought it down everything is back to normal 🙂

I have an ambari managed 10 node hdp cluster (2.5.0) deployed in amazon EC2 instance centos 7. I have mounted an EBS volume under /data mount point and configured that as namenode and datanode directories. Everything was working fine. For some reason I have to change the EBS volume. So I followed the below steps. 1- Stop all service from ambari 2- Mount the new EBS volume under /data mount point 3- Restart all amazon ec2 instances 4- Start services using ambari. After 4 th step my hdfs is not working properly and hence hbase service is also failing. I am not getting any errors in either datanode or namenode start. And sees the status in ambari as green. When I do hdfs dfsadmin -report I get following output.

@Jay Kumar SenSharma In addition to that my hbase service is not able to start due to the below error. The EBS volume I have changed is the data node directory I configured. And I had data in hbase before doing that. In order to avoid that do I need to anything else ? 8-02-20 11:56:44,465 WARN [Thread-70] hdfs.DFSClient: DataStreamer Exception

I have set up ambari cluster with 9 nodes. Everything was working fine perfectly. For some reason I have to change data directory I have given for hdfs to another disc. I have stopped all the services and mounted new hard disc properly to the same old mount point. I have rebooted all the nodes after mounting new device. Now when I start all services again. All the services getting failed. What could be the reason ? Do I need to do any step here ?

@George Vetticaden : I have tried the above steps in my hcp cluster with hdp - 2.5.3.0 along with metron UI manager. I don't need to do step 2 right ? This is the same as the enrichment configuration done via metron UI right ? My enrichment configuration json is as follows. This will suffice here for step 2 right ? I ran the file loader script without -n option. /usr/metron/0.1BETA/bin/flatfile_loader.sh -i whois_ref.csv -t enrichment -c t -e extractor_config.json {
"enrichment": {
"fieldMap": {},

"triageConfig": {
"riskLevelRules": [],

}
},

}
<br> Unfortunately my enrichment is not working. My kafka topic message coming in indexing topic is as follows. {"code":200,"method":"GET","enrichmentsplitterbolt.splitter.end.ts":"1518783891207","enrichmentsplitterbolt.splitter.begin.ts":"1518783891207","is_alert":"true","url":"https:\/\/www.woodlandworldwide.com\/","source.type":"newtest","elapsed":2033,"ip_dst_addr":"182.71.43.17","original_string":"1518783890.244 2033 127.0.0.1 TCP_MISS\/200 49602 GET https:\/\/www.woodlandworldwide.com\/ - HIER_DIRECT\/182.71.43.17 text\/html\n","threatintelsplitterbolt.splitter.end.ts":"1518783891211","threatinteljoinbolt.joiner.ts":"1518783891213","bytes":49602,"enrichmentjoinbolt.joiner.ts":"1518783891209","action":"TCP_MISS","guid":"40ff89bf-71a1-4eec-acfd-d89886c9ce7f","threatintelsplitterbolt.splitter.begin.ts":"1518783891211","ip_src_addr":"127.0.0.1","timestamp":1518783890244}

@Otto Fowler Thanks a lot for your support. I finally resolved the issue. Root cause was in the sensor configuration json we have to add "timestampField": "timestamp" explicitly under key 'parserConfig'. If I add that and stopping and starting sensor using metron UI solved the issue.
Then only like you said parser will create proper timestamp in long. Now I get the below error in indexing bolt when checked via storm UI. Any idea about what could be causing this ? java.io.FileNotFoundException:

@Otto Fowler How can I restart parser topology in storm ? I could not see an option in storm UI. I restarted both storm server & metron components using ambari after changing the sensor configuration using metron UI. But the same error message is coming. Do I need to restart any other component or missing any step ?

@Otto Fowler I have added the sensor configuration directly via command line without using metron UI after seeing this issue. I am talking about step 4 in this link. Parser bolt worked correctly. It pushed parsed message to configured kafka topic 'indexing'. But Indexing bolt did not work. It gave me the below error in 'indexing' topic.

@Otto Fowler Thanks for the reply. As per the code snippet it will invalidate if <0 plus not instance of long right ? My squid log message is 1517911793.839 2186 127.0.0.1 TCP_MISS/200 48493 GET https://www.woodlandworldwide.com/ - HIER_DIRECT/182.71.43.17 text/html And my grok parser expression is SQUID_DELIMITED %{NUMBER:timestamp}.*%{INT:elapsed} %{IP:ip_src_address} %{WORD:action}/%{NUMBER:code} %{NUMBER:bytes} %{WORD:method} %{NOTSPACE:url}.*%{IP:ip_dst_addr} It creates the timestamp as 1517911793.839 . So here the failing check would be of long right ? Why a check like that is present ? Squid's timestamp format is like this only right ? What should I do here in such case ? I even tried directly pushing a message without decimal in timestamp. But that also failed the validation. Another interesting thing is If I add storm config directly ( Not vial UI ) Validation works fine.
