Thomas Graves commented on YARN-370:
------------------------------------
Sorry the only other thing I can think of that would matter is having security
on. I had security on and the code that throws the exception is looking at the
Token, so if you don't have security on you probably won't see it.
Other then that it was running any simple job - sleep, wordcount.

> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacityscheduler
> Affects Versions: 2.0.3-alpha
> Reporter: Thomas Graves
> Assignee: Zhijie Shen
> Priority: Blocker

> I was running 2.0.3-SNAPSHOT with the capacity scheduler configured with
> minimum allocation size 1G. The AM size was set to 1.5G. I didn't specify
> resource calculator so it was using DefaultResourceCalculator. The am launch
> failed with the error below:
