Subject [jira] [Commented] (YARN-1424) RMAppAttemptImpl should precompute a zeroed ApplicationResourceUsageReport to return when attempt not active
Date Sat, 07 Jun 2014 01:41:02 GMT

    [ https://issues.apache.org/jira/browse/YARN-1424?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14020632#comment-14020632
] 

Karthik Kambatla commented on YARN-1424:
----------------------------------------

Looks like the test failure is due to using 0 instead of -1 for the resource-usage-report.
[~jlowe] - is there any particular reason we chose to use -1? Do you think changing it to
0 is reasonable?

> 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.
