>             Project: HBase
>          Issue Type: Bug
>          Components: Replication
>    Affects Versions: 2.0.0, 1.4.0

> 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.
