[jira] [Created] (HBASE-10335) AuthFailedException in zookeeper may block replication forever

Liu Shaohui created HBASE-10335:
-----------------------------------

             Summary: AuthFailedException in zookeeper may block replication forever
                 Key: HBASE-10335
                 URL: https://issues.apache.org/jira/browse/HBASE-10335
             Project: HBase
          Issue Type: Bug
          Components: Replication, security
            Reporter: Liu Shaohui


ReplicationSource will rechoose sinks when encounted exceptions during skipping edits to the current sink. But if the  zookeeper client for peer cluster go to AUTH_FAILED state, the ReplicationSource will always get  AuthFailedException. The ReplicationSource does not reconnect  the peer, because reconnectPeer only handle ConnectionLossException and SessionExpiredException. As a result, the replication will print log:

2014-01-14,12:07:06,892 INFO org.apache.hadoop.hbase.replication.regionserver.ReplicationSource: Getting 0 rs from peer cluster # 20
2014-01-14,12:07:06,892 INFO org.apache.hadoop.hbase.replication.regionserver.ReplicationSource: Slave cluster looks down: 20 has 0 region servers

and be blocked forever.

I think other places may have same problems for not handling AuthFailedException in zookeeper. eg: HBASE-8675.
