Jonathan Lawlor commented on HBASE-13362:
-----------------------------------------

+1, looks good to me.

Question, should we also add an entry for this new configuration to hbase-default.xml? I'm just thinking, as a user, how would I know about this new configuration value and the semantics behind it?

> With the recent problems we've been seeing client/server result size mismatch, I was thinking: Why was this not a problem with scanner caching?
> There are two reasons:
> # number of rows is easy to calculate (and we did it correctly)
> # caching is only controlled from the client, never set on the server alone
> We did fix both #1 and #2 in HBASE-13262.
> Still, I'd like to discuss the following:
> * default the client sent max result size to 2mb
> * remove any server only result sizing
> * continue to use hbase.client.scanner.max.result.size but enforce it via the client only (as the name implies anyway).
> Comments? Concerns?
