Subject [jira] [Commented] (YARN-8792) Revisit FairScheduler QueuePlacementPolicy
Date Wed, 27 Mar 2019 12:13:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-8792?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16802707#comment-16802707

Wilfred Spiegelenburg commented on YARN-8792:
---------------------------------------------

None of these changes fit into the integrated way we currently implement the rules in the
FS and CS.
As part of YARN-8948, YARN-9298 and finally integrated in YARN-8967 this has been changed.
Both schedulers now use the same placement manager and placement rule code. The placement
of the application in a queue is moved out of the FS also.

> Fair scheduler use `QueuePlacementPolicy` to map a request to queue. There are several
problems:
>  # The termination of the responsibility chain should bind to the assigning result instead
of the rule.
>  # It should provide a reason when rejecting a request.
>  # Still need more useful rules:
>  ## RejectNonLeafQueue
>  ## RejectDefaultQueue
>  ## RejectUsers
>  ## RejectQueues
>  ## DefaultByUser
