Robert Joseph Evans commented on MAPREDUCE-4128: ------------------------------------------------ The reason you patch does not apply is because you made a change to hadoop-tools, which the pre-commit build chocks on. One issue I saw was TaskFinishedEvent constructor added in a new attemptId, but no javadocs for that param. It is minor but would be a -1 in the Precommit-build. I will run the precommit build myself and post the results. > AM Recovery expects all attempts of a completed task to also be completed. > -------------------------------------------------------------------------- > > Key: MAPREDUCE-4128 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4128 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2 > Affects Versions: 3.0.0 > Reporter: Bikas Saha > Assignee: Bikas Saha > Fix For: 3.0.0 > > Attachments: MAPREDUCE-4128.patch > > > The AM seems to assume that all attempts of a completed task (from a previous > AM incarnation) would also be completed.
