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

             Summary: Increase "yarn.nodemanager.disk-health-checker.max-disk-utilization-per-disk-percentage"
to avoid host-related failures on MiniMRCluster
                 Key: HBASE-19317
                 URL: https://issues.apache.org/jira/browse/HBASE-19317
             Project: HBase
          Issue Type: Bug
          Components: integration tests, test
            Reporter: Josh Elser
            Assignee: Josh Elser
             Fix For: 2.0.0-beta-1


YARN (2.7.4, at least) defaults to asserting at least 10% of the disk usage free on the local
machine in order for the NodeManagers to function.

On my development machine, despite having over 50G free, I would see the warning from the
NM that all the local dirs were bad which would cause the test to become stuck waiting to
submit a mapreduce job. Surefire would eventually kill the process.

We should increase this value to avoid it causing us headache.
