> Ranger's ranger-admin-services.sh relies on being able to log to $RANGER_LOG_DIR for the stop command. If $RANGER_LOG_DIR doesn't exist (which can happen when bin/clean.sh runs), then testdata/bin/kill-ranger-server.sh will fail with this error:
> {noformat}
> Getting pid from /tmp/rangeradmin.pid ..
> Found Apache Ranger Admin Service with pid 23263, Stopping it...
> /opt/Impala-Toolchain/cdp_components-40643771/ranger-2.3.0.7.2.18.0-41-admin/ews/ranger-admin-services.sh: line 129: /home/joemcdonnell/upstream/Impala/logs/cluster/ranger/catalina.out: No such file or directory
> Shutdown in progress. Will check after 2 secs again..
> Shutdown in progress. Will check after 2 secs again..
> ...
> Initial kill failed, getting serious now...
> Apache Ranger Admin Service with pid 23263 has been stopped.{noformat}
> The missing directory error means that the original stop command never even executed. Ranger will not stop on its own, so this will always wait for 30 seconds and then do a hard kill. This delays stopping Ranger for no reason.
> If kill-ranger-server.sh creates RANGER_LOG_DIR before running ranger-admin-services.sh, then the original stop command succeeds immediately.
