Ravi Gummadi updated MAPREDUCE-3121:

    Attachment: 3121.v3.patch

Attaching new patch. Addressed all the review comments except the integration tests for other
components. Will raise a separate JIRA for them as the current patch is already having tests
that check the basic functionality of the patch.

> This is akin to MAPREDUCE-2413 but for YARN's NodeManager. We want to minimize the impact
of transient/permanent disk failures on containers. With larger number of disks per node,
the ability to continue to run containers on other disks is crucial.
