Chang Zong created HDFS-11589:
---------------------------------
Summary: 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?
