Wei Yan updated YARN-2126:
--------------------------
Description:
When an application is removed, the FSLeafQueue updates its amResourceUsage.
{code}
if (runnableAppScheds.remove(app.getAppSchedulable())) {
// Update AM resource usage
if (app.getAMResource() != null) {
Resources.subtractFrom(amResourceUsage, app.getAMResource());
}
return true;
}
{code}
If an application is removed before it has a chance to start its AM, the
amResourceUsage shouldn't be updated.
