-----------------------------------

             Summary: OYA: Introduce <mr-jars /> inside <launcher />
                 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 an XSD extension within {{workflow.xsd}}:
* an {{xs:boolean}} valued {{<mr-jars />}} within {{<launcher />}} within {{<application />}}
* defaults to {{false}}
* its value is used within [{{JavaActionExecutor.needToAddMRJars()}}|https://github.com/apache/oozie/blob/oya/core/src/main/java/org/apache/oozie/action/hadoop/JavaActionExecutor.java#L1342]
