ramkrishna.s.vasudevan commented on HBASE-11920:
------------------------------------------------
Actually if you see the javadoc for postScannerOpen
{code}
* @return an RegionScanner instance to use instead of the base scanner if
* overriding default behavior, null otherwise
{code}
in preStoreScannerOpen
{code}
a KeyValueScanner instance to use or {@code null} to use the default
implementation
{code}
So the caller is handling this, if not null then the returned value is used in
the caller. So ideally we should return null in the base impl and ensure the
caller is handling it.

> If we want to create internal replication endpoints other than the one
> created thro configuration we may need new hooks. This is something like an
> internal scanner that we create during compaction so that the actual
> compaction scanner can be used as a delegator.
