Subject Re: Issues with Decommissioning MAchine

figured it out. We were facing a scenario where some of the files had
replication factor more than the actual number of datanodes.

https://issues.apache.org/jira/browse/MAPREDUCE-2845

That is why the Namenode was unable to decommission the machine, since it
could not get the replica count settled.
