Description

We had an issue where a regionserver on our destination side failed to refresh the keytabs. The source side's replication got stuck because the HBaseInterClusterReplicationEndpoint only chooses new sinks if there happens to be a ConnectException but the SaslException is an IOException, which does not choose new sinks.

I'll put up a patch to check this exception and choose new sinks.
