Guanghao Zhang commented on HBASE-16415:
----------------------------------------
bq. making this a general interface vs. encapsulating this functionality in the
new endpoint entirely
We don't need design too early. If we need this interface in the future, we can
abstract it to the parent class in the future. Now encapsulating this
functionality in the new endpoint entirely is enough. Thanks.

> 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());
> }
> }
