Anoop Sam John commented on HBASE-13303:
----------------------------------------

I am also not sure whether the math in the loop(client side) will create any issue.  Was just
pointing out.. Let me look more closely at this math Andy.  Will report back if any issue.

> 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.
