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 ! -- 不学习，不知道 -- 不学习，不知道
