Subject: Re: Hive hbase handler (0.92.0)

There is something amiss. The client has seen a ZK transaction ID far ahead o=
f what the ZK server thinks is the current epoch. Usually this happens if yo=
u blow away ZK storage and restart it, ie you are creating transient ZK quor=
ums. A client that continues to run will remember the zxid of the old ZK quo=
rum while the new one will start again with a zxid of 0. Another way this ca=
n happen is if you've some how mixed two distinct ZK quorums in your HBase c=
onfiguration: it contains the names of servers in two distinct quorums. Thos=
e two ZK clusters will have uncorrelated zxids.

Check your ZK configuration.

Best regards,
