[jira] Commented: (HBASE-2847) Put added after a delete is overshadowed if its timestamp is older than than that of the tombstone

["Jonathan Gray (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-2847?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12889924#action_12889924 ] 

Jonathan Gray commented on HBASE-2847:
--------------------------------------

This is probably the hardest behavior to change because it requires looking at the type, not just the timestamp / memstore stamp / storefile order.

I think we should fix multiple version issues first, for puts, and then consider this.

> If we delete a row and then at a later time add to the row a cell that has a timestamp that is older than the delete, the addition will not be seen; the tombstone will prevent the newer addition being returned.
> IMO, this is non-intuitive.  We should fix.
