             Summary: java-opts and java-opt in the Java action don't always work properly in YARN
                 Key: OOZIE-1794
                 URL: https://issues.apache.org/jira/browse/OOZIE-1794
             Project: Oozie
          Issue Type: Bug
    Affects Versions: trunk
            Reporter: Robert Kanter
            Assignee: Robert Kanter


Currently, when you set {{<java-opts>}} or {{<java-opt>}} in the Java action, it essentially appends these to {{mapred.child.java.opts}} in the launcher job.  

In YARN, this property is deprecated in favor or {{mapreduce.map.java.opts}} and {{mapreduce.reduce.java.opts}}.  And if {{mapreduce.map/reduce.java.opts}} is set, {{mapred.child.java.opts}} will be ignored.  So in a YARN cluster where mapred-site.xml has {{mapreduce.map.java.opts}} set to something, {{<java-opts>}} and {{<java-opt>}} won't work at all.  

We should have {{<java-opts>}} and {{<java-opt>}} append to both {{mapred.child.java.opts}} and {{mapreduce.map.java.opts}}.
