-------------------------------------

             Summary: HBaseInterClusterReplicationEndpoint: Do not retry the 
whole batch of edits in case of RejectedExecutionException
                 Key: HBASE-14953
                 URL: https://issues.apache.org/jira/browse/HBASE-14953
             Project: HBase
          Issue Type: Bug
          Components: Replication
    Affects Versions: 2.0.0, 1.2.0, 1.3.0
            Reporter: Ashu Pachauri
            Assignee: Ashu Pachauri


When we have wal provider set to multiwal, the ReplicationSource has multiple 
worker threads submitting batches to HBaseInterClusterReplicationEndpoint. In 
such a scenario, it is quite common to encounter RejectedExecutionException 
because it takes quite long for shipping edits to peer cluster compared to 
reading edits from source and submitting more batches to the endpoint. 
The logs are just filled with warnings due to this very exception.

Since we subdivide batches before actually shipping them, we don't need to fail 
and resend the whole batch if one of the sub-batches fails with 
RejectedExecutionException. Rather, we should just retry the failed 
sub-batches.
