> Key: OOZIE-2869
> URL: https://issues.apache.org/jira/browse/OOZIE-2869
> Project: Oozie
> Issue Type: Sub-task
> Components: action
> Affects Versions: 5.0.0
> Reporter: Andras Piros
> Assignee: Andras Piros
> Fix For: 5.0.0b1
>
> Attachments: OOZIE-2869.001.patch, OOZIE-2869.amend.001.patch

>
> Since Oozie On YARN doesn't fire a map only job to fire all the other
> applications (hence the transition from {{LauncherMapper}} to
> {{LauncherAM}}), no need to bundle the MapReduce JARs within Oozie's default
> sharelib.
> Nevertheless, it's a common, but discouraged use case that MapReduce tasks
> are fired using Java Action. So we need some default {{mapreduce}} sharelib
> that can be used by customers after OOZIE-2601 will have been implemented:
> # by default, create a sharelib named {{mapreduce}} which will contain the MR
> jars using local paths as those jars are on every machine
> # users can add mapreduce jars to any action using
> {{oozie.action.sharelib.for.ACTION}} just like now. They could add MR jars
> into Java, Spark or Shell actions easily
