I am also facing same issue, i got it resolved as below.
SystemExit because of multiple logstash running.

check for the .lock file at path/var/lib/logstash ,
delete .lock file
rm .lock

Now configure pipeline.yaml as below (remove # from first line)

	- pipeline.id: main
	  path.config: "/etc/logstash/logstash-its.conf"

Now restart logstash
systemctl restart logstash
