----------------------------------
Summary: CapacityScheduler app submission fails when min alloc
size not multiple of AM size
Key: YARN-370
URL: https://issues.apache.org/jira/browse/YARN-370
Project: Hadoop YARN
Issue Type: Bug
Components: capacityscheduler
Affects Versions: 3.0.0, 2.0.3-alpha
Reporter: Thomas Graves
Priority: Critical
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: at

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