Subject [jira] [Commented] (YARN-521) Augment AM - RM client module to be able to request containers only at specific locations
Date Mon, 08 Jul 2013 21:07:49 GMT

    [ https://issues.apache.org/jira/browse/YARN-521?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13702424#comment-13702424
] 

Sandy Ryza commented on YARN-521:
---------------------------------

I uploaded a new patch that adds in the checks mentioned by Bikas and Alejandro.  I moved
the parameter documentation to constructors.  Regarding the priority comments, I think the
new ones are clearer, but they're out of the scope this JIRA so I reverted them and I'll argue
somewhere else if I want to make that change.  Regarding renaming allRacks to dedupedRacks,
the code is doing the same thing as it was before for requests with locality relaxed, but
I had to move some things around to accommodate disabling locality relaxation.
