Sean Busbey reassigned HBASE-13446:
-----------------------------------

    Assignee: Lars Hofhansl

Assigning to you [~lhofhansl] based on your "I'll take a stab at it" over on HBASE-13262. If doing it the ref guide instead of the mailing list isn't your thing, unassign and I'll try.

> Should we put a warning somewhere (mailing list? book?) about this? Something like:
> IF (client OR server is <= 0.98.11/1.0.0) AND server has a smaller value for hbase.client.scanner.max.result.size than client does, THEN scan requests that reach the server's hbase.client.scanner.max.result.size are likely to miss data. In particular, 0.98.11 defaults hbase.client.scanner.max.result.size to 2MB but other versions default to larger values, so be very careful using 0.98.11 servers with any other client version.
