------------------------------------
Assignee: Jonathan Eagles
> Log a warning if Xmx is configured incorrectly.
> ------------------------------------------------
>
> Key: TEZ-1508
> URL: https://issues.apache.org/jira/browse/TEZ-1508
> Project: Apache Tez
> Issue Type: Bug
> Reporter: Hitesh Shah
> Assignee: Jonathan Eagles
> Labels: newbie
>
> 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).
