             Summary: testdata/bin/kill-hive-server.sh should remove the HiveServer2 pid file
                 Key: IMPALA-11621
                 URL: https://issues.apache.org/jira/browse/IMPALA-11621
             Project: IMPALA
          Issue Type: Improvement
          Components: Infrastructure
    Affects Versions: Impala 4.2.0
            Reporter: Joe McDonnell


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.
