Uninstalling DataStax Distribution of Apache Cassandra 3.x

Steps for uninstalling Cassandra by installation type.

Select the uninstall method for your type of installation:

Uninstalling Debian- and RHEL-based packages

Use this method when you have installed Cassandra using APT or Yum.

Stop the Cassandra service:
```
$ sudo service cassandra stop
```
Make sure all services are stopped:
```
$ ps auwx | grep cassandra
```
If services are still running, use the PID to kill the service:
```
$ sudo kill cassandra_pid
```

Remove the library and log directories:

$ sudo rm -r /var/lib/cassandra
$ sudo rm -r /var/log/cassandra

Use this method when you have installed Apache Cassandra 3.0 using the binary tarball.

Stop the node:

$ ps auwx | grep cassandra
$ sudo  kill cassandra_pid
