$ sudo pkill -9 couchbase-server

$ ps -ef | grep couchbase

----------------------------------------------------------------------

HOWEVER, 'sudo pkill -u couchbase' does.

$ sudo pkill -u couchbase
$ ps -ef | grep couchbase

This fix is not very critical at all because the kill command is only used in the scenario in which a start fails. See https://github.com/openstack/trove/blob/ea51b7e625b6be4415a665cd36dab44742b0362e/trove/guestagent/datastore/couchbase/service.py#L180-L185
