    Resolution: Duplicate

> Unable to remove dead node after datanode decommission 
> -------------------------------------------------------
>                 Key: HDFS-11589
>                 URL: https://issues.apache.org/jira/browse/HDFS-11589
>             Project: Hadoop HDFS
>          Issue Type: Improvement
>    Affects Versions: 2.4.0
>            Reporter: Chang Zong
> After successfully decommissioned a datanode, the state of that node in web ui(http://<NameNode_FQDN>:50070)
is changed to "decommissioned". Then I stopped the datanode service in that host and the state
is changed to "Dead", and the number of last contact keeps increasing. I tried to remove the
hostname from the dfs.exclude and run "hdfs dfsadmin -refreshNodes" again, but that dead node
is still there. 
> Any way to solve that problem without restarting the whole cluster?
