[ https://issues.apache.org/jira/browse/OOZIE-2869?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Peter Bacsko updated OOZIE-2869:
--------------------------------
Parent Issue: OOZIE-2889 (was: OOZIE-1770)
> OYA: Introduce default mapreduce sharelib
> -----------------------------------------
>
> 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
> Fix For: 5.0.0
>
>
> 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
