Subject [jira] [Commented] (YARN-2139) [Umbrella] Support for Disk as a Resource in YARN
Date Fri, 21 Nov 2014 23:15:38 GMT

    [ https://issues.apache.org/jira/browse/YARN-2139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14221561#comment-14221561
] 

Karthik Kambatla commented on YARN-2139:
----------------------------------------

[~leftnoteasy] - completely agree with both Arun and you on the spindle-locality-affinity
front. The design doc hints at it, but doesn't cover it in as much detail as it should. I
am all up for accomplishing that too here, I can work on fleshing out the locality-affinity
pieces as we start getting the remaining parts in. 

I am considering starting the development on a feature-branch so we have a chance to change
things before merging into trunk and branch-2.  Are people okay with that?

> YARN should consider disk as another resource for (1) scheduling tasks on nodes, (2)
isolation at runtime, (3) spindle locality.
