stack resolved HBASE-2569.
--------------------------
Resolution: Unresolved
Closing as unresolved. Refers to an old version of hbase.
> Improper error handling in face of version mismatch between the client and
> the server
> -------------------------------------------------------------------------------------
>
> Key: HBASE-2569
> URL: https://issues.apache.org/jira/browse/HBASE-2569
> Project: HBase
> Issue Type: Bug
> Components: Client
> Reporter: Benoit Sigoure
> Priority: Minor
>
> I use trunk, and every once in a while, when I upgrade my test instance of
> HBase, my clients end up in a seemingly endless loop when instantiating an
> {{HTable}} instance:
> {code}
> 10/05/18 23:42:46 DEBUG zookeeper.ZooKeeperWrapper: Read ZNode
> /hbase/root-region-server got 192.168.0.7:61322
> 10/05/18 23:42:47 DEBUG client.HConnectionManager$TableServers: Root region
> location changed. Sleeping.
> 10/05/18 23:42:48 DEBUG client.HConnectionManager$TableServers: Wake. Retry
> finding root region.
> {code}
> I'm pretty certain that the code throws an appropriate exception to complain
> about the version mismatch but it must be getting eaten somewhere and the
> code probably applies the usual retry logic instead of throwing up its hands
> in the air and immediately giving up, as I think it should.
