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.

How about we add a note in the ref guide for upgrades and for
troubleshooting?
