Using nodetool with authentication

How to use nodetool with authentication.

After configuring JMX authentication, using nodetool requires the -u and -p options to the nodetool commands.

Procedure

Run nodetool using a pre-configured JMX username and password for <username> and <password>:

nodetool -u <username> -pw <password>

For Cassandra 3.6 and later, the username and password can be an internally configured Cassandra role and password.

Note: In Cassandra 3.0.8 and later, a user designated readonly access can run nodetool info so that cluster monitoring is available. In earlier versions, the user must have readwrite permission.
