all operations on the (JT + NN) node.

I create a file with all (DN + TT) nodes listed in it called  hosts.include
I also create a file with all the nodes need to be decommissioned in it
called hosts.exclude

and then I setting the* mapred.hosts* and *dfs.hosts* to *hosts.include*and set
* mapred.hosts.exclude* and* dfs.hosts.exclude* to *hosts.exclude*

and then I restart he JT

and then refresh nodes with sudo -u hdfs hadoop dfsadmin -refreshNodes

after that, there is no effect, the cluster still there without any changes.

do I forget something ? I successfully decommissioned 3 nodes last week
through the same way , but, why it has no effect today ?

thank you for your reply in advance !
