Subject [jira] [Commented] (YARN-7142) Support placement policy in yarn native services
Date Thu, 22 Mar 2018 22:28:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7142?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16410503#comment-16410503

Wangda Tan commented on YARN-7142:
----------------------------------

Thanks [~gsaha], my comments: 
1) Placement policy removed from Service? How user to specify common placement policies for
components.
2) Compatibility of the placement policy?
3) validatePlacementPolicy:
- Should we enforce target tag name == self component name?
4) Remove expression name from Example.md:
- {{"name": "CA1"}}
5) Mark unsupported APIs from the documentation/definition.
6) Add node partition to PlacementConstraint. Ref: org.apache.hadoop.yarn.api.resource.PlacementConstraints.PlacementTargets#nodePartition
7) tags => targetTags
8) Use SchedulingRequest when ANY component uses placement policy.
