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?
