Answer 1

If it's only a process and not a service you could do something like

$ ps auwx | grep cassandra
$ sudo kill <pid>

where <pid> is what you get from ps auwx | grep cassandra

This will stop the process. Then you have to start it again

$ cd <install_location>
$ bin/cassandra

where <install_location> is where you have installed cassandra

if is a service: service cassandra restart

Try to use these commands:

$ service dse start/stop/restart
