Duo Zhang commented on HBASE-19095:
-----------------------------------

Sounds good. Maybe we also need to tell CP users the compaction type, 'basic' 
or something else.

And how do we control whether to drop cells when doing in memory compaction? We 
do not use StoreScanner in basic mode? If we use the same code base for 
different compaction types, then it is possible that CP users can drop cells 
even if we are doing a basic in memory compaction. Is it acceptable?

Thanks.
