Subject [jira] [Commented] (YARN-6268) Container with extra data
Date Fri, 03 Mar 2017 08:06:45 GMT

    [ https://issues.apache.org/jira/browse/YARN-6268?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15893888#comment-15893888
] 

冯健 commented on YARN-6268:
--------------------------

MRAppMaster's solution use request‘s Priority to identify container's role,  I think that
was not graceful, and maybe can't work  in complicated case. 
if you  have many kinds of containers to launch,  you need map every container to one unique
priority .  if we need decide container's running mode by context(eg: we don't know what process
to launch before resource request), use priority doesn't work.
