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

             Summary: Handle container requests that request more resources than available in the cluster
                 Key: MAPREDUCE-4578
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4578
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.0.0-alpha, 0.23.0
            Reporter: Hitesh Shah


In heterogenous clusters, a simple check at the scheduler to check if the allocation request is within the max allocatable range is not enough. 

If there are large nodes in the cluster which are not available, there may be situations where some allocation requests will never be fulfilled. Need an approach to decide when to invalidate such requests. For application submissions, there will need to be a feedback loop for applications that could not be launched. For running AMs, AllocationResponse may need to augmented with information for invalidated/cancelled container requests.
