> 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.
