Note:

For tarball installations, execute the command from the install_location/bin directory.

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 will invalidate the counter cache, and the system will start saving all counter keys.

Examples
