@Robert Levas I had already checked there was no entry in the serviceconfigmapping table serviceconfigmapping where service_config_id=979 AND config_id=42; I am getting results when I execute SELECT config_id, version_tag, version, type_name FROM clusterconfig WHERE config_id=42; I am trying to dig into this a little deeper. Will post updates. ... View more

Dear All, I am trying to kerberize our HDP cluster ( HDP 2.5) and I am running into an error in one of the steps. I went with the option of Manage Kerberos Principal and Keytabs manually. I have followed all the steps including distributing the principals manually on all the hosts. Following is the step where I am stuck I am also attaching the ambari server logs for reference. I see the following message in the log and i checked the ambari db this entry does not exist in the table. Any suggestions ambari-server.zip Thanks, Anand AmbariJpaLocalTxnInterceptor:188 - [DETAILED ERROR] Internal exception (2) : org.postgresql.util.PSQLException: ERROR: duplicate key value violates unique constraint "serviceconfigmapping_pkey" Detail: Key (service_config_id, config_id)=(979, 42) already exists. ...

Dear All, I recently upgraded our cluster (3 node not secure) from HDP 2.3 to 2.5. After the upgrade was finalized and when i was restarting some of the services I saw that zookeeper went down on one of the nodes with the following errors in the log 2016-10-04 05:38:06,427 - INFO [main:QuorumPeer@1038] - initLimit set to 10 2016-10-04 05:38:06,439 - INFO [main:FileSnap@83] - Reading snapshot /hadoop/zookeeper/version-2/snapshot.4400000000 2016-10-04 05:38:06,556 - ERROR [main:QuorumPeer@530] - Unable to load database on disk java.io.IOException: The current epoch, 45 is less than the accepted epoch, 32 at org.apache.zookeeper.server.quorum.QuorumPeer.loadDataBase(QuorumPeer.java:527) at org.apache.zookeeper.server.quorum.QuorumPeer.start(QuorumPeer.java:473) at org.apache.zookeeper.server.quorum.QuorumPeerMain.runFromConfig(QuorumPeerMain.java:153) at org.apache.zookeeper.server.quorum.QuorumPeerMain.initializeAndRun(QuorumPeerMain.java:111) at org.apache.zookeeper.server.quorum.QuorumPeerMain.main(QuorumPeerMain.java:78) 2016-10-04 05:38:06,558 - ERROR [main:QuorumPeerMain@89] - Unexpected exception, exiting abnormally java.lang.RuntimeException: Unable to run quorum server at org.apache.zookeeper.server.quorum.QuorumPeer.loadDataBase(QuorumPeer.java:531) at org.apache.zookeeper.server.quorum.QuorumPeer.start(QuorumPeer.java:473) at org.apache.zookeeper.server.quorum.QuorumPeerMain.runFromConfig(QuorumPeerMain.java:153) at org.apache.zookeeper.server.quorum.QuorumPeerMain.initializeAndRun(QuorumPeerMain.java:111) at org.apache.zookeeper.server.quorum.QuorumPeerMain.main(QuorumPeerMain.java:78) Caused by: java.io.IOException: The current epoch, 45 is less than the accepted epoch, 32 at org.apache.zookeeper.server.quorum.QuorumPeer.loadDataBase(QuorumPeer.java:527) ... 4 more 2016-10-04 05:50:32,198 - INFO [main:FourLetterWordMain@43] - connecting to localhost 2181 2016-10-04 06:01:35,510 - INFO [main:FourLetterWordMain@43] - connecting to localhost 2181 I saw that there is a JIRA https://issues.apache.org/jira/browse/ZOOKEEPER-2307, do i need to apply this patch.
