Cassandra didn't stop at Centos

I am working on Centos (CentOS Linux 7.3.1611 release) and trying to use Cassandra (3.0.9). The setup was pretty easy to follow and so far so good. But when I start Cassandra (using systemctl start cassandra

) the service is: " active (exited)

" instead of " active (running)

".

[root@localhost ~]# systemctl status cassandra
● cassandra.service - SYSV: Starts and stops Cassandra
   Loaded: loaded (/etc/rc.d/init.d/cassandra; bad; vendor preset: disabled)
   Active: active (exited) since Wed 2017-05-03 12:06:54 CEST; 5s ago
     Docs: man:systemd-sysv-generator(8)
  Process: 9337 ExecStart=/etc/rc.d/init.d/cassandra start (code=exited, status=0/SUCCESS)

May 03 12:06:54 localhost.localdomain systemd[1]: Starting SYSV: Starts and stops Cassandra...
May 03 12:06:54 localhost.localdomain su[9344]: (to cassandra) root on none
May 03 12:06:54 localhost.localdomain cassandra[9337]: Starting Cassandra: OK
May 03 12:06:54 localhost.localdomain systemd[1]: Started SYSV: Starts and stops Cassandra.

      

        
        
        
      

    

I decided to restart the service using systemctl restart cassandra

but there is a problem with the stop process:

[root@localhost ~]# systemctl restart cassandra
[root@localhost ~]# systemctl status cassandra
● cassandra.service - SYSV: Starts and stops Cassandra
   Loaded: loaded (/etc/rc.d/init.d/cassandra; bad; vendor preset: disabled)
   Active: active (exited) since Wed 2017-05-03 12:15:50 CEST; 32s ago
     Docs: man:systemd-sysv-generator(8)

  Process: 9508 ExecStart=/etc/rc.d/init.d/cassandra start (code=exited, status=0/SUCCESS)

May 03 12:15:49 localhost.localdomain systemd[1]: cassandra.service: control process exited, code=exited status=1
May 03 12:15:49 localhost.localdomain systemd[1]: Unit cassandra.service entered failed state.

May 03 12:15:50 localhost.localdomain cassandra[9508]: Starting Cassandra: OK
May 03 12:15:50 localhost.localdomain systemd[1]: Started SYSV: Starts and stops Cassandra.

      

        
        
        
      

    

Do you have an idea to solve this problem? Thank:)

A good day.
