Nodetool

Usage

usage: nodetool [(-pwf <passwordFilePath> | –password-file <passwordFilePath>)]
[(-p <port> | –port <port>)] [(-h <host> | –host <host>)] [(-pw <password> | –password <password>)] [(-pp | –print-port)] [(-u <username> | –username <username>)] <command> [<args>]

The most commonly used nodetool commands are:
