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.

The nodetool invalidatecountercache command clears the counter cache, and the system will start saving all counter keys.
