[jira] [Created] (HBASE-17698) ReplicationEndpoint choosing sinks

churro morales created HBASE-17698:
--------------------------------------

             Summary: ReplicationEndpoint choosing sinks
                 Key: HBASE-17698
                 URL: https://issues.apache.org/jira/browse/HBASE-17698
             Project: HBase
          Issue Type: Bug
    Affects Versions: 2.0.0, 1.4.0
            Reporter: churro morales


The only time we choose new sinks is when we have a ConnectException, but we have encountered other exceptions where there is a problem contacting a particular sink and replication gets backed up for any sources that try that sink

HBASE-17675 occurred when there was a bad keytab refresh and the source was stuck.

Another issue we recently had was a bad drive controller on the sink side and replication was stuck again.  

Is there any reason not to choose new sinks anytime we have a RemoteException?  I can understand TableNotFound we don't have to choose new sinks, but for all other cases this seems like the safest approach.
