Not sure we want this in the docs. It only affects 0.98.11 (not .10 and not .12) and only with clients before .11. A note on the mailing lists seems to be more appropriate. (Not feeling strongly, though).

0.98.11 certainly exposes the problem clearly, but I think it exists in all the prior versions as well.  If your server is configured with a smaller value for hbase.client.scanner.max.result.size than your client, and a scan reaches that value, you're in trouble.

> 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.
