> 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:
> Application application_1359688216672_0001 failed 1 times due to Error
> launching appattempt_1359688216672_0001_000001. Got exception: RemoteTrace:
