Hadoop QA commented on OOZIE-3681:
----------------------------------
PreCommit-OOZIE-Build started
> Revise yarn.app and mapreduce property overrides in Oozie
> ---------------------------------------------------------
>
> Key: OOZIE-3681
> URL: https://issues.apache.org/jira/browse/OOZIE-3681
> Project: Oozie
> Issue Type: Improvement
> Affects Versions: 5.2.1
> Reporter: Janos Makai
> Assignee: Janos Makai
> Priority: Major
> Attachments: OOZIE-3681-001.patch
>
>
> According to the following documentation
> [https://hadoop.apache.org/docs/r3.1.2/hadoop-yarn/hadoop-yarn-site/ResourceModel.html]
> oozie.launcher.override.memory.mb and oozie.launcher.override.vcores are
> outdated so the goal is to extend them with currently accepted property keys.
> The current keys should be in the beginning of the list to have the highest
> priority. Legacy overrides need to at end of the lists:
> oozie.launcher.mapreduce.map.memory.mb &
> oozie.launcher.mapreduce.map.cpu.vcores &
> oozie.launcher.mapreduce.map.java.opts
> The old keys should *not* be deleted to preserve backward compatibility of
> Oozie and workflow configuration.
