Arun Ramakrishnan updated HDFS-1290:
------------------------------------
Description:
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.
