Synopsis

nodetool [options] assassinate [args]
Table 1. Options
Short Long Description
-h --host Hostname or IP address
-p --port Port number
-pwf --password-file Password file path
-pw --password Password
-u --username User name
Note:
  • For tarball installations, execute the command from the install_location/bin directory.
  • 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.
  • nodetool assassinate operates 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.

Description

The nodetool assassinate command is a tool of last resort. Only use this tool to remove a node from a cluster when removenode is not successful.

Examples
