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