> 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.
