Make NodeManager identify the failed disks becoming goodno

                 Key: MAPREDUCE-3441
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3441
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: nodemanager
    Affects Versions: 0.23.0
            Reporter: Ravi Gummadi

MAPREDUCE-3121 makes NodeManager identify disk failures. But once a disk goes down, it is
marked as failed forever. To reuse that disk (after it becomes good), NodeManager needs restart.
This JIRA is to improve NodeManager to reuse good disks(which could be bad some time back).
