> HBaseInterClusterReplicationEndpoint: Do not retry the whole batch of edits

> 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
> Priority: Critical
> Attachments: HBASE-14953-V1.patch, HBASE-14953-V2.patch
>
>
> 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.
