Allen Wittenauer commented on YARN-3330: ---------------------------------------- This shouldn't be yarn specific. I'd HIGHLY recommend bumping this up to a full issue into the HADOOP project so that: a) goes into common b) has higher visibility > 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 > Attachments: pdiff_patch.py > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
