Note: 
          
- If a username and password for RMI authentication are set explicitly in the cassandra-env.sh file for the host, then you must specify credentials.
 - The repair and rebuild commands can affect multiple nodes in the cluster.
 - Most nodetool commands operate on a single node in the cluster if -h is not used to identify one or more other nodes. If the node from which you issue the command is the intended target, you do not need the -h option to identify the target; otherwise, for remote invocation, identify the target node, or nodes, using -h.
 
Example:
      
    nodetool -u username -pw password describering demo_keyspace
