Cassandra Cluster Manager (CCM) is a script that allows users to easily create, manage and destroy a small Cassandra cluster on a local machine. Developers and administrator typically run ccm on their laptops or desktops so they can quickly run tests against a specific version of a Cassandra cluster.

nodetool is a command-line utility that allows administrators to run commands against a Cassandra node including check the status of a cluster (status), run repairs (repair) and display node information (info).

For more information on CCM, see https://github.com/riptano/ccm. For other nodetool commands, see The nodetool utility. Cheers!
