• Cleanup : Now that everything is done and there is relatively low traffic on the
database, it is a good time to clean the useless data from each node as follows:
$ /opt/cassandra/bin/nodetool -h 10.10.21.228 cleanup
$ /opt/cassandra/bin/nodetool -h 10.10.21.169 cleanup
$ /opt/cassandra/bin/nodetool -h 10.10.21.206 cleanup
$ /opt/cassandra/bin/nodetool -h 10.10.21.7 cleanup
Now, we are done with adding a new node to the system.
