Subject [jira] [Commented] (YARN-6595) [API] Add Placement Constraints at the application level
Date Tue, 07 Nov 2017 01:42:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6595?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16241328#comment-16241328
] 

Konstantinos Karanasos commented on YARN-6595:
----------------------------------------------

Thanks for the patch, [~asuresh].

It looks good, some minor comments only:
* Let's remove the test from the {{BasePBImplRecordsTest}}. I think we can add a simple test
at the {{TestAMRMClient}}.
* In {{RegisterApplicationMasterRequest}}, rename to get/setPlacementConstraints (Map is not
really needed in the naming), and add some comments.
* Change the first lines of the equals of CardinalityConstraint to be the same as the other
classes (do the !instanceof instead of the ==null and getClass()).
* Some line refactoring in {{RegisterApplicationMasterRequestPBImpl}} is not needed.
* In {{RegisterApplicationMasterRequest}}, import the Unstable interface as we do for the
Stable already.
