>                 Key: HDFS-1290
>                 URL: https://issues.apache.org/jira/browse/HDFS-1290
>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: namenode
>    Affects Versions: 0.20.1
>         Environment: fedora 12
>            Reporter: Arun Ramakrishnan
>
> after i add the list of decom nodes to exclude list and -refreshNodes.
> In the WebUI the decom/excluded nodes show up in both the live node list and the dead
node list.
> when I do -report from the command line.
> """
>   Datanodes available: 14 (20 total, 6 dead)
> """
> The problem here is that is only 14 nodes total including the 6 added to the exclude
list. 
> Now, in the node level status for each of the nodes, the excluded nodes say 
> """"
>  Decommission Status : Normal
> """"
>  But, all the nodes say the same thing. I think if it said something like "in-progress",
it would be more informative. 
> note. one thing distinguishing these excluded nodes is that they all report 0 or 100%
for all the values in -report.
> Cause, at this point i know from https://issues.apache.org/jira/browse/HDFS-1125 that
one may have to restart the cluster to completely remove the nodes.
> But, i have no clue when i should restart.
> Ultimately, whats needed is some indication to when the decomission is complete so that
all references to the excluded nodes ( from excludes, slaves ) and restart the cluster.
