  2. Run the Hadoop cluster configuration script as shown below: 
    disable_vol.sh [-y] [--hadoop-mgmt-node node] [--user admin-user] [--pass admin-password] [--port mgmt-port-num] --yarn-master node volName
    For example, 
    disable_vol.sh --hadoop-mgmt-node mgmt-node --yarn-master yarn-node HadoopVol
