Ray Chiang updated YARN-1424:
-----------------------------
Attachment: YARN1424-01.patch
First version of a potential patch.
- Moves DUMMY_APPLICATION_RESOURCE_USAGE_REPORT RMAppImpl to RMServerUtils.
Cannot move this to ApplicationResourceUsageReport, since it exists in the
hadoop-yarn-api module as opposed to everything else being in the
hadoop-yarn-server module.
- Uses the reference in RMAppImpl and RMAppAttemptImpl.
- No unit tests in this particular patch file.
> RMAppAttemptImpl should precompute a zeroed ApplicationResourceUsageReport to
> return when attempt not active

>
> RMAppImpl has a DUMMY_APPLICATION_RESOURCE_USAGE_REPORT to return when the
> caller of createAndGetApplicationReport doesn't have access.
> RMAppAttemptImpl should have something similar for
> getApplicationResourceUsageReport.
> It also might make sense to put the dummy report into
> ApplicationResourceUsageReport and allow both to use it.
> A test would also be useful to verify that
> RMAppAttemptImpl#getApplicationResourceUsageReport doesn't return null if the
> scheduler doesn't have a report to return.
