> With HIVE-22193, Hive added a graceful stop functionality that also changed some startup scripts. Hive now keeps a file with the HiveServer2's pid and checks to see if it is already running before starting up. testdata/bin/kill-hive-server.sh uses testdata/bin/kill-java-service.sh, and it doesn't know to remove the pid file. Since testdata/bin/kill-java-service.sh would fail if it was unable to stop HiveServer2, it should be safe to remove the pid file after that command succeeds.
> If we don't remove the pid file, the OS might reuse the pid and this could interfere with HiveServer2 startup.
