Wangda Tan commented on YARN-2500:
----------------------------------
Highlight major changes for easier review:
* Properly setup and check label expression according to ResourceRequest,
ApplicationSubmissionContext and queue default label expression
** Located in {{ApplicationMasterService}},
{{RMServerUtils#validateResourceRequest}}
* In the past, ResourceRequest of AM container created in two places (one in
{{RMAppManager}}, another one in {{RMAppAttemptImpl}}), when trying to allocate
resource from YarnScheduler, the 2nd ResourceRequest doesn't normalized. Now
reduced this to only one: ResourceRequest will be created in {{RMAppManager}}
only, and it will pass ResourceRequest to RMAppImpl to allocate resource
* Check if a queue has permission to access all labels in label-expression of a
ResourceRequest, located in {{SchedulerUtils.validateResourceRequest}}
* Added getLabels() and getDefaultLabelExpression to Queue
* Added get/set NodeLabelManager in RMContext
