Thank you so much and it is resolved. But why it is not replicating ? When it is keeping under /oldWALs directory it should replicate right ? Can you please give me clarification.     Best Regards, Vinod ... View more

Hello @smdas    Thank you so much for your response. Followed above steps and find below details,   ls /hbase/replication [peers, rs] ls /hbase/replication/peers [] Now i have deleted replication in ZNODE and added hbase.replication as false in hbase-site.xml and restarted HBase. Find below details after restart, ls /hbase/replication [peers, rs] ls /hbase/replication/peers []   And now i can see it is cleared and empty under /hbase/oldWALs directory in hdfs.   But if you can observe attached screen shot, That is not enabled right? Any differences?     Regards, Vinod   ... View more

Hello @Shelton    I have added above property in yarn-site.xml for nodemanager and restarted, Still i see same issue and same logs in nodemanager and it is in unknown state,   WARN org.apache.hadoop.yarn.server.nodemanager.containermanager.AuxServices: The Auxilurary Service named 'mapreduce_shuffle' in the configuration is for class class org.apache.hadoop.mapred.ShuffleHandler which has a name of 'httpshuffle'. Because these are not the same tools trying to send ServiceData and read Service Meta Data may have issues unless the refer to the name in the config   Please give me your valuable response.   Thanks, Vinod ...

Hello @Shelton    Any suggestions ? My only doubt is, As other nodemanagers are running fine in the cluster why these newly added nodemanagers were going to unknown state?   Regards, Vinod ... View more

Hello @Shelton    Yes we are using YARN and other Nodemanagers are up and running with same configurations but for newly added nodes we are facing above logs and they are going to unknown state.   Yes i verified the above parameter but i dont see the above parameter but in yarn configurations page, I can see " Enable Shuffle Auxiliary Service " was enabled.   Please suggest me your comments.   Thanks, Vinod ...

Hello @rblough    First of all thank you so much for your response..!!   1. The X and Y environments are having different HBase versions. 2. HBase X version is 1.3.1 and HBase Y Version is 1.0.0 3. We are not clearing the table but following below steps,   echo "disable '$1'" | hbase shell echo "restore_snapshot '$1_SNAPSHOT_$DATE'" | hbase shell echo "enable '$1'" | hbase shell   Daily we are doing the same but sometimes we are seeing the counts mismatch. So, we are doing truncating and restoring the same snapshots and working fine in Y environment.   Please help us your inputs.   Thanks & Regards, Vinod   ... View more
