Andrew Purtell commented on HBASE-13303:
----------------------------------------

Agreed. 

bq. Only issue is we might not be honoring the actual max result size what user specified. Especially when the tags are returned back. 

Yes, this could be significantly more than expected. 

Also agreed we can handle this better as part of HBASE-13262 or a similar 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.
