Description

Preconditions:
Cassandra service is running successfully.

Cassandra service is erroneously started when already running via:
service cassandra start

/var/run/cassandra/cassandra.pid is overwritten with new pid. The original cassandra process continues to run. The recorded pid is not running.

Because the recorded pid is incorrect, its impossible to stop cassandra via:
service cassandra stop

Before starting cassandra, the script should ensure that its not already running.
