Description

HDFS Federation documentation
http://hadoop.apache.org/docs/r2.6.0/hadoop-project-dist/hadoop-hdfs/Federation.html
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
