      Description

      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.

Failing the application.

      It looks like the launchcontext for the app didn't have the resources rounded up.
