Role logs would be really helpfull to analyze the issue. P.S: MirrorMaker will not start by default. MirrorMaker will be used to mirror the Data from one Kafka to another

Adding to @jmartin1938, stop un-used CDH services, it give some more RAM to the required services

Now Cloudera is not proving any type of coupons

I was going through Cloudera SPI document and i found out it is possible to develop our own plugin for our cloud environment (CloudFoundry). So is my understanding is right..? if yes, kindly suggest which all are the things i need to consider to build the plugin. Below are the links for docs how to write a cloud provider plugin for cloudera director Cloudera director spi

I am using Sentry, so when i enable `hive.server2.enable.impersonation` it's showing "Hive Impersonation is enabled for Hive Server2 role 'HiveServer2 '. Hive Impersonation should be disabled to enable Hive authorization using Sentry"

kchaitanya · ‎01-22-2017

According to the Sentry documentation " When Sentry is enabled, you must use Beeline to execute Hive queries. Hive CLI is not supported with Sentry and must be disabled". Is there any offcial way to disable Hive CLI.

I fixed the issue, by doing below Seems Level Database DB is corrupted, and did below mv /var/lib/cloudera-service-monitor /var/lib/cloudera-service-monitor.moved mv /var/lib/cloudera-host-monitor /var/lib/cloudera-host-monitor.moved Then restarted the services again, it worked

kchaitanya · ‎01-09-2017

I have sucessfully installed Kerberos and integrated with Cloudera Mnagaer, while starting the cloudera manager services i'm getting below error for Host Monitor and Service Monitor Host Monitor error log Jan 9, 5:24:56.202 PM ERROR com.cloudera.cmon.firehose.Main Error creating LevelDB timeseries store in directory /var/lib/cloudera-host-monitor/ts org.fusesource.leveldbjni.internal.NativeDB$DBException: Invalid argument: /var/lib/cloudera-host-monitor/ts/ts_entity_metadata: does not exist (create_if_missing is false) at org.fusesource.leveldbjni.internal.NativeDB.checkStatus(NativeDB.java:194) at org.fusesource.leveldbjni.internal.NativeDB.open(NativeDB.java:212) at org.fusesource.leveldbjni.JniDBFactory.open(JniDBFactory.java:168) at com.cloudera.cmon.tstore.leveldb.LDBUtils.openVersionedDB(LDBUtils.java:246) at com.cloudera.cmon.tstore.leveldb.LDBTimeSeriesMetadataStore.openMetadataDB(LDBTimeSeriesMetadataStore.java:149) at com.cloudera.cmon.tstore.leveldb.LDBTimeSeriesMetadataStore.<init>(LDBTimeSeriesMetadataStore.java:139) at com.cloudera.cmon.firehose.Main.main(Main.java:450) Service Monitor error log Jan 9, 5:24:56.475 PM ERROR com.cloudera.cmon.firehose.Main Error creating LevelDB timeseries store in directory /var/lib/cloudera-service-monitor/ts org.fusesource.leveldbjni.internal.NativeDB$DBException: Invalid argument: /var/lib/cloudera-service-monitor/ts/ts_entity_metadata: does not exist (create_if_missing is false) at org.fusesource.leveldbjni.internal.NativeDB.checkStatus(NativeDB.java:194) at org.fusesource.leveldbjni.internal.NativeDB.open(NativeDB.java:212) at org.fusesource.leveldbjni.JniDBFactory.open(JniDBFactory.java:168) at com.cloudera.cmon.tstore.leveldb.LDBUtils.openVersionedDB(LDBUtils.java:246) at com.cloudera.cmon.tstore.leveldb.LDBTimeSeriesMetadataStore.openMetadataDB(LDBTimeSeriesMetadataStore.java:149) at com.cloudera.cmon.tstore.leveldb.LDBTimeSeriesMetadataStore.<init>(LDBTimeSeriesMetadataStore.java:139) at com.cloudera.cmon.firehose.Main.main(Main.java:450) What is the issue

I hope it's not a good idea, as it says "Enforce that parcel dependencies are satisfied and conflicts are prevented when activating parcels. Parcel relations (Depends, Conflicts, and Replaces) can be defined the manifests of parcel repositories. Cloudera Manager can also enforce some default relations if none are defined in the manifest" Anyway thanks for the tip 🙂

kchaitanya · ‎01-02-2017

@sroweni did all, downloaded parcel and distributed to all nodes, while activating the parcel i'm getting CDH (lower than 5.12) parcel required for SPARK2 (2.0.0.cloudera1-1.cdh5.7.0.p0.113931) is not available

kchaitanya · ‎01-02-2017

Followed same institutions. Downloaded CSD jar file and moved to /opt/cloudera/csd and restarted the server and management services. But no luck

kchaitanya · ‎01-02-2017

Did you find any solution

kchaitanya · ‎12-19-2016

So if i want to continue with Firewall (iptables) ON, i need to open ports for all service which are installing newly, which will put more load on the nodes. By implementing security methods (Kerberos), can i secure my cluster

kchaitanya · ‎12-16-2016

Did you find anything, to view hive or other passwords

kchaitanya · ‎12-01-2016

You can try with this tiny.cloudera.com/yarn-tuning-guide https://www.cloudera.com/documentation/enterprise/5-5-x/topics/cdh_ig_yarn_tuning1.html
