> Key: HBASE-4459
> URL: https://issues.apache.org/jira/browse/HBASE-4459
> Project: HBase
> Issue Type: Bug
> Components: io
> Reporter: Jonathan Gray
> Assignee: ramkrishna.s.vasudevan
> Priority: Critical
> Fix For: 0.92.0
>
> Attachments: 4459-v2.patch.txt, 4459.txt
>
>
> 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.
