> There are about 90 classes/codes in HbaseObjectWritable currently and Byte.MAX_VALUE
is 127.  In addition, anyone wanting to add custom classes but not break compatibility might
want to leave a gap before using codes and that's difficult in such limited space.
> Eventually we should get rid of this pattern that makes compatibility difficult (better
client/server protocol handshake) but we should probably at least bump this to a short for
0.94.
