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

             Summary: NM to recognise when it can't span process and stop accepting containers
                 Key: YARN-1073
                 URL: https://issues.apache.org/jira/browse/YARN-1073
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager
    Affects Versions: 2.1.0-beta
         Environment: OS/X with not enough file handles
            Reporter: Steve Loughran


when creating too many containers with a claimed resource use of 0 RAM or vCores, the NM got to the state where exec() was continually failing -but nothing seemed to recognise this and blacklist the node.

Something should be noting that all container launches for an app/container are failing and do something. While AMs can/should code this, NM failure is something at the YARN-level
