             Summary: YARN minicluster doesn't bail out if all the NM disks are 
                 Key: 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.
