Description

1. command is wrong

 $HADOOP_PREFIX/bin/hdfs dfsadmin -refreshNameNode <datanode_host_name>:<datanode_rpc_port>

Correct command is : hdfs dfsadmin -refreshNameNode's'

2.command is wrong

 $HADOOP_PREFIX/sbin/hadoop-daemon.sh --config $HADOOP_CONF_DIR --script $HADOOP_PREFIX/bin/hdfs start balancer 

Correct command is : start-balancer.sh -policy

3. Reference link to balancer for further details is wrong

Note that Balancer only balances the data and does not balance the namespace. For the complete command usage, see balancer.
