Lost nodes list and count not updated
-------------------------------------

                 Key: MAPREDUCE-3271
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3271
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 0.23.0
            Reporter: Ramya Sunil
             Fix For: 0.23.0


When nodemanagers are lost, the "Lost Nodes" list and the count is not incremented. Either
we,

1. Fix the lost nodes list when a nodemanager is lost - The problem with tracking lost nodes
is, if the nodemanager joins back, there would be duplicate entries in active and lost nodes
with different port numbers.
2. Do not track lost nodemanagers
