> Key: HADOOP-3500
> URL: https://issues.apache.org/jira/browse/HADOOP-3500
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 0.17.0
> Environment: linux-2.6.9
> Reporter: lixiangna
> Original Estimate: 72h
> Remaining Estimate: 72h
>
> try to decommission a node by the following the steps:
> (1) write the hostname of node which will be decommissioned in a file (the
> exclude file)
> (2) specified the absolute path of the exclude file as a configuration
> parameter dfs.hosts.exclude.
> (3) run "bin/hadoop dfsadmin -refreshNodes".
> It is surprising that the node is found both in the "Live Datanodes" with "In
> Service" status, and in the "Dead Datanodes" of the dfs namenode web ui. When
> copy new data to the HDFS, its Used size is increasing as other
> un-decommissioned nodes. Obviously it is in service. Restarting the HDFS or
> waiting a long time(two day) havn't make the decommission yet.
> the more strange thing, If nodes are configured as the include nodes by
> similar steps, then these include nodes and
> the exclude node are all only in the "Dead Datanodes" lists.
> I did many times tests in both 0.17.0 and 0.15.1. The results is same. So i
> think there maybe bugs.
