Subject [jira] [Created] (YARN-1781) NM should allow users to specify max disk utilization for local disks
Date Tue, 04 Mar 2014 18:17:28 GMT
Varun Vasudev created YARN-1781:
-----------------------------------

             Summary: NM should allow users to specify max disk utilization for local disks
                 Key: YARN-1781
                 URL: https://issues.apache.org/jira/browse/YARN-1781
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
            Reporter: Varun Vasudev


This is related to YARN-257(it's probably a sub task?). Currently, the NM does not detect
full disks and allows full disks to be used by containers leading to repeated failures. YARN-257
deals with graceful handling of full disks. This ticket is only about detection of full disks
by the disk health checkers.

The NM should allow users to set a maximum disk utilization for local disks and mark disks
as bad once they exceed that utilization. At the very least, the NM should at least detect
full disks.
