In HIVE-22193, Hive added graceful shutdown for HiveServer2. This modified some of the startup scripts to maintain a pid file. On startup, it verified that the pid is not already running. Impala uses the hive startup script, but it kills HiveServer2 with testdata/bin/kill-java-service.sh. If the pid file outlives the process, then the OS may reuse the pid and this can cause problems on startup. This modifies testdata/bin/kill-hive-server.sh to remove the pid file. testdata/bin/kill-java-service.sh would fail if it did not kill HiveServer2, so it should be safe to remove the pid file after the kill-java-service.sh call. Testing: - Verified the hiveserver2.pid file is removed after shutting down.
