    [ https://issues.apache.org/jira/browse/HBASE-18649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16160684#comment-16160684

ramkrishna.s.vasudevan commented on HBASE-18649:
------------------------------------------------

bq.What we do for 2.0? Can we do any deprecations?
Will prepare a patch for deprecating the KV using classes and change the  name to Cell every
where. Infact I should have done that in this patch. Will update it accordingly.
bq. Should it be a CellSortReducer? This stuff internal or external? 
Will change to CellSortReducer and this stuff is external. So in 2.0 we should deprecate and
say moving to CellSortReducer.
bq.KeyValueWritableComparable to be CellWC
Yes. 
bq.We have to do this stuff? 530	}
Probably I will not do the changes for including the tags. I felt that was a bug or something
that was missed. 
bq.ExtendedCellWrapper the right name? MapReduceCell?
Yes. Will rename it.
