Anoop Sam John commented on HBASE-13303:
----------------------------------------
[~apurtell]
Still on the client side we will use CellUtil#estimatedHeapSizeOf for the Cell
size calc right? When the scan is issued by the super user we will send back
the tags (so that the tool like Export will export tags also) In such a case
there will be size mismatch and issues?
> Fix size calculation of results on the region server

> One of the problems in the parent is due to different size calculation
> between client and server when HFilev3 is used.
> Since tags are _never_ shipped to the client in a scan, we can have special
> size function (or a flag on the current one) that does not include the tags
> and the tags meta information (the length is what causes the issue), so that
> client and server will always calculate the same size.
> I'll make a patch within the hour, unless somebody beats me to it.
> [~apurtell], FYI.
