> On HBaseInterClusterReplicationEndpoint.replicate, if no sinks are returned
> by ReplicationSinkManager, say remote peer is not available, we log message
> below and return false to source shipper thread, which then keeps retrying,
> flooding source RS log with the below messages:
> {noformat}
> WARN
> org.apache.hadoop.hbase.replication.regionserver.HBaseInterClusterReplicationEndpoint:
> No replication sinks found, returning without replicating. The source should
> retry with the same set of edits.
> {noformat}
> This condition could also cause ReplicationSinkManager.chooseSinks to blow an
> NPE.
