[jira] [Commented] (YARN-6592) Rich placement constraints in YARN

    [ https://issues.apache.org/jira/browse/YARN-6592?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16297761#comment-16297761 ]

-----------------------------------

Hi [~kkaranasos], [~asuresh], [~leftnoteasy]

What's the relationship of this one to YARN-3409? I am a bit confused with existing node labels and new node attributes. It looks to me like that node labels can be represented by attributes easily, they are just boolean KV attributes. Attributes seemed to be more flexible. So will this one be depending on YARN-3409?
