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

I've restarted the precommit job for this change. let's see if TestSplitTableRegionProcedure
has gone bad.

> It would be nice to replicate tables from one namespace to another namespace.
> Example:
> Master cluster, namespace=default, table=bar
> Slave cluster, namespace=dr, table=bar
> Replication happens in class ReplicationSink:
>   public void replicateEntries(List<WALEntry> entries, final CellScanner cells,
...){
>     ...
>     TableName table = TableName.valueOf(entry.getKey().getTableName().toByteArray());
>     ...
>     addToHashMultiMap(rowMap, table, clusterIds, m);
>     ...
>     for (Entry<TableName, Map<List<UUID>, List<Row>>> entry :
rowMap.entrySet()) {
>       batch(entry.getKey(), entry.getValue().values());
>     }
>    }
