Subject [jira] [Commented] (YARN-2500) [YARN-796] Miscellaneous changes in ResourceManager to support labels
Date Mon, 06 Oct 2014 20:13:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-2500?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14160858#comment-14160858

Wangda Tan commented on YARN-2500:

Regarding comments from [~vinodkv],
bq. As with other patches, Labels -> NodeLabels. You'll need to change all of the following:...
bq. ApplicationMasterService: There are multiple this.rmContext.getRMApps().get(appAttemptId.getApplicationId()
calls in the the allocate method. Refactor to avoid dup calls.
bq. TestSchedulerUtils: testValidateResourceRequestWithErrorLabelsPermission: Why are "" and
" " accepted when only x and y are recognized labels?
Empty label expression "" should be accept by any queue, and " " will be trimmed to empty.
bq. Given we don't support yet other features in ResourceRequest for the AM container like
priority, locality, shall we also hard-code them to AM_CONTAINER_PRIORITY, ResourceRequest.ANY
respectively too?
Agree, now set values to default for priority/#container/resource-name/relax-locality
bq. Can we add test-case for num-containers, priority, locality for AM container?
Added test "testScheduleTransitionReplaceAMContainerRequestWithDefaults" in RMAppAttemptImpl.

Please kindly review,
