Jonathan Gray commented on HBASE-4459: -------------------------------------- - Why is Queue added within the scope of this JIRA? Seems unrelated. - Can you remove the unnecessary import re-org at the top? - Can we have a unit test which shows the backwards compatibility of this? Thanks for working on this Ram. > HbaseObjectWritable code is a byte, we will eventually run out of codes > ----------------------------------------------------------------------- > > 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.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. -- This message is automatically generated by JIRA.
