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).
