Subject [jira] [Updated] (YARN-2003) Support for Application priority : Changes in RM and Capacity Scheduler
Date Sat, 18 Jul 2015 08:00:10 GMT

Sunil G updated YARN-2003:
    Attachment: 0024-YARN-2003.patch

Hi [~leftnoteasy]
I have done some more analysis on test failure. As per the YARN-3533, fix is done in {{launchAM}}
of MockRM. I was using MockRM apis in below way earlier.
RMApp app1 = rm.submitApp(1 * GB, appPriority1);
MockAM am1 = rm.sendAMLaunched(app1.getCurrentAppAttempt()

{{launchAM}} already wraps nm.nodeHeartbeat and sendAMLaunched. And after YARN-3533, its assured
that attempt state is SCHEDULED before calling nodeHeartbeat. If we directly use as per above
code segment, its some times possible that before app attempt is SCHEDULED, nm heartbeats
arrives and attempt may be still ALLOCATED.

Hence I changed my test cases to use this wrapped api {{launchAM}}  from MockRM. Uploading
a patch with same.

Context and store.
> Later this can be used by Scheduler.
