Subject [jira] [Commented] (YARN-5324) Stateless router policies implementation
Date Wed, 21 Sep 2016 22:31:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5324?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15511406#comment-15511406

Carlo Curino commented on YARN-5324:
------------------------------------

[~subru] thanks for the follow up. 

I think I have address all your asks with the exception of the suggestion around adding {{selectSubcluster}}.

After implementing the other refactoring you suggested the {{getHomeSubcluster()}} implementations
are 
down to 5-30 lines and an external method call I don't think will improve readabiliy by much.
