You can also see the passed parameters if you do `ps aux` on the slave during the execution (but you need to catch the right time to catch the execution). Currently, when you set or in the Java action, it essentially appends these to mapred.child.java.opts in the launcher job. YARN monitors memory of your running containers. Please check the job conf (job.xml link) of hive jobs in the JobTracker UI to see whether mapred.child.java.opts was correctly propagated to MapReduce.
