> Users may incorrectly configure Xmx for tasks. Xmx should in most cases be less than the container/task size given that YARN will kill containers that exceed the memory limits. 
> Given that we already parse the java opts to detect Xmx in the java opts, it should be trivial to add a check if the value is valid and log a warning if not ( for both the Tez AM and the vertices in a DAG).
