-----------------------------
Hi [~aw], thanks for the suggestion! I will definitely bump this up after I
finished the two issues raised above.
> Implement a protobuf compatibility checker to check if a patch breaks the
> compatibility with existing client and internal protocols

> 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.
