Need a RM->AM channel to inform AMs about faulty/unhealthy/lost nodes
---------------------------------------------------------------------

                 Key: MAPREDUCE-3353
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3353
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: applicationmaster, mrv2, resourcemanager
    Affects Versions: 0.23.0
            Reporter: Vinod Kumar Vavilapalli
             Fix For: 0.23.1


When a node gets lost or turns faulty, AM needs to know about that event so that it can take
some action like for e.g. re-executing map tasks whose intermediate output live on that faulty
node.
