---------------------------
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.
