J.Andreina created HDFS-9043:
--------------------------------

             Summary: Doc updation for commands in HDFS Federation
                 Key: HDFS-9043
                 URL: https://issues.apache.org/jira/browse/HDFS-9043
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: documentation
            Reporter: J.Andreina
            Assignee: J.Andreina
            Priority: Minor


1. command is wrong 
{noformat}
 $HADOOP_PREFIX/bin/hdfs dfsadmin -refreshNameNode <datanode_host_name>:<datanode_rpc_port>
{noformat}
Correct command is : hdfs dfsadmin -refreshNameNode's'

2.command is wrong 
{noformat}
 $HADOOP_PREFIX/sbin/hadoop-daemon.sh --config $HADOOP_CONF_DIR --script $HADOOP_PREFIX/bin/hdfs
start balancer 
{noformat}
Correct command is : *hdfs balancer -policy*

3. Reference link to balancer for further details is wrong
{noformat}
Note that Balancer only balances the data and does not balance the namespace. For the complete
command usage, see balancer.
{noformat}

4. URL is not proper 
{noformat}
Similar to the Namenode status web page, when using federation a Cluster Web Console is available
to monitor the federated cluster at http://<any_nn_host:port>/dfsclusterhealth.jsp.
{noformat}
