Anoop Sam John commented on HBASE-9874:
---------------------------------------

Yes Andy doing a naive merge now. Taking the tags from old cell and the 
corresponding cell's tags in Increment/Append. Merge all into the resultant new 
cell.  Then we can give chance to CP. It is like there can be a ACL tag in old 
cell and new ACL tag in the corresponding cell comin in Append/Increment. The 
core will just merge both into the new cell. Then the CP hook can decide what 
to do with these 2. (Which one should go finally)..  Doing exactly same in the 
visibility labels patch.   Pls review patch V2

> Append and Increment operation drops Tags
