Sandy Ryza commented on YARN-560:
---------------------------------
Ravi,
The patch looks good to me. Nit: can you use block comments ( /** ... */ )
instead of single line comments over the tests?
> If AM fails due to overrunning resource limits, error not visible through UI
> sometimes

> I had a case where an MR AM eclipsed the configured memory limit. This caused
> the AM's container to get killed, but nowhere accessible through the web UI
> showed these diagnostics. I had to go view the NM's logs via ssh before I
> could figure out what had happened to my application.
