Description
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).
