------------------------------------

             Summary: YARN minicluster doesn't bail out if all the NM disks are dead
                 Key: YARN-2839
                 URL: https://issues.apache.org/jira/browse/YARN-2839
             Project: Hadoop YARN
          Issue Type: Bug
          Components: test
    Affects Versions: 2.6.0
            Reporter: Steve Loughran


Some jenkins tests of mine have been failing deep in the resource localization process. Iif
all the disks of the NMs are considered bad they refuse to work, but the Yarn Minicluster
doesn't fail itself.

YARN-90 assumes that the NM disks will come back. This isn't likely to hold in a short-lived
mini cluster —better to have it probe the NMs and fail if they aren't healthy.
