             Summary: ZkBaseDataAccessor#set() should throw BadVersionException 
instead of return false in case of version mismatch
                 Key: HELIX-514
                 URL: https://issues.apache.org/jira/browse/HELIX-514
             Project: Apache Helix
          Issue Type: Bug
            Reporter: Zhen Zhang


ZkBaseDataAccessor#set() should throw BadVersionException instead of return 
false in case of version mismatch, since caller (e.g. 
HelixGroupCommit#commit()) may need to distinguish between fatal error and 
transient error (e.g. version mismatch) so it can retry.
