Synopsis

nodetool [options] invalidatecountercache
Tarball and Installer No-Services path:
installation_location/resources/cassandra/bin
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 Remote JMX agent username.
-- Separates an option from an argument that could be mistaken for a option.
Note:
  • For tarball installations, execute the command from the installation_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 invalidatecountercache 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 invalidatecountercache command clears the counter cache, and the system will start saving all counter keys.

Examples

 $ nodetool -u username -pw password invalidatecountercache
