-----------------------------

             Summary: HDFS Federation : Command mentioned to add a NN to 
existing federated cluster is wrong 
                 Key: HDFS-7998
                 URL: https://issues.apache.org/jira/browse/HDFS-7998
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: documentation
            Reporter: Ajith S
            Assignee: Ajith S
            Priority: Minor


HDFS Federation documentation has the following command to add a namenode to 
existing cluster

> $HADOOP_PREFIX_HOME/bin/hdfs dfadmin -refreshNameNode 
> <datanode_host_name>:<datanode_rpc_port>

this command is incorrect, actual correct command is 

> $HADOOP_PREFIX_HOME/bin/hdfs dfsadmin -refreshNamenodes 
> <datanode_host_name>:<datanode_rpc_port>

need to update the same in documentation
