------------------------------------
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.
