Subject [jira] [Commented] (HBASE-9874) Append and Increment operation drops Tags
Date Sun, 03 Nov 2013 04:21:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9874?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13812259#comment-13812259

Anoop Sam John commented on HBASE-9874:

bq.but let's put the postMutationBeforeWAL hook in on this JIRA
Sure. Can put the hook also in this Jira. Initially I thought that will be covered as part
of HBASE-7662 or some other sub task. 
bq.We are going to be duplicating the work of the naive merge anyhow 
Yes agree.  But we are not sure whether there will be some CP impls available to do this merge.
In general when user adds some other tags and do increment of the cell, we should not drop
the tags in new cell. That is why I raised this Jira.. I think you are agreeing here too...

Next Patch I will put the CP hook also.  Thanks Andy for the review.
