             Summary: Implement a protobuf compatibility checker to check if a patch breaks the compatibility with existing client and internal protocols
                 Key: YARN-3330
                 URL: https://issues.apache.org/jira/browse/YARN-3330
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Li Lu
            Assignee: Li Lu


Per YARN-3292, we may want to start YARN rolling upgrade test compatibility verification tool by a simple script to check protobuf compatibility. The script may work on incoming patch files, check if there are any changes to protobuf files, and report any potentially incompatible changes (line removals, etc,.). We may want the tool to be conservative: it may report false positives, but we should minimize its chance to have false negatives.
