stack commented on HBASE-5974:
------------------------------
bq. If you all say that is fine, I can change.. We need to clearly document
these 2 methods with its importance and what to do wrt this etc.
The class is marked private and used serverside only so its ok adding methods
to the Interface?
But if you feel strongly about it, keep it as is. it looks a bit ugly but at
least the uglyness is contained inside HRegionServer.
Make a new patch and lets get it committed. Thanks Anoop.
> Scanner retry behavior with RPC timeout on next() seems incorrect

> I'm seeing the following behavior:
> - set RPC timeout to a short value
> - call next() for some batch of rows, big enough so the client times out
> before the result is returned
> - the HConnectionManager stuff will retry the next() call to the same server.
> At this point, one of two things can happen: 1) the previous next() call will
> still be processing, in which case you get a LeaseException, because it was
> removed from the map during the processing, or 2) the next() call will
> succeed but skip the prior batch of rows.
