Subject [jira] Created: (HADOOP-1184) Decommission fails if a block that needs replication has only one replica

Decommission fails if a block that needs replication has only one replica
-------------------------------------------------------------------------

                 Key: HADOOP-1184
                 URL: https://issues.apache.org/jira/browse/HADOOP-1184
             Project: Hadoop
          Issue Type: Bug
          Components: dfs
            Reporter: dhruba borthakur


If the only replica of a block resides on a node being decommissioned, then the decommission
command does not complete. The blocks do not get added to neededReplication because neededReplications.update()
believes that the number of current replicas is zero.
