A command line interface for managing a cluster.
The nodetool utility is a command line interface for managing a cluster.
- Package installations: nodetool [(-h <host> | --host <host>)] [(-p <port> | --port <port>)] [(-pwf <passwordFilePath> | --password-file <passwordFilePath>)] [(-u <username> | --username <username>)] [(-pw <password> | --password <password>)] <command> [<args>]
- Tarball installations: Execute the command from install_location/bin
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.
