Subject [jira] [Commented] (YARN-392) Make it possible to schedule to specific nodes without dropping locality
Date Tue, 12 Feb 2013 02:15:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-392?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13576299#comment-13576299

Bikas Saha commented on YARN-392:

Since you have already gone ahead and assigned it to yourself, why dont you take a shot.

If YARN-393 gets solved then my guess is that this jira might get automatically resolved.
However, YARN-393 is even more complex and potentially hard to fix.

It would be good if you can post your ideas/approach first instead of a patch. This jira might
be tricky and so discussing alternatives and agreeing on one of them would be a good exercise.
I will try to post an alternative to this jira too.

> Currently its not possible to specify scheduling requests for specific nodes and nowhere
else. The RM automatically relaxes locality to rack and * and assigns non-specified machines
to the app.
