Some Jenkins jobs running Impala tests have hit an error when running testdata/bin/kill-ranger-server.sh:

19:25:50 Wow, even kill -9 failed, giving up! Sorry..{noformat}
The job in question has never started Ranger. This is calling kill-ranger-server.sh via testdata/bin/kill-all.sh from testdata/bin/run-all.sh as part of starting the minicluster.

One possibility is that the /tmp/rangeradmin.pid is leftover from an old run and the pid has been reused. The ranger-admin-services.sh script doesn't seem to remove the pid file after stopping Ranger.

If this is the cause, then we can customize the location of the Ranger pid file and make sure it gets deleted properly.
