Resolution: Not A Problem
Affects Version/s: 0.20.1
Fix Version/s: None
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.
