---------------------------------------

             Summary: HS2 should log when shutting down due to OOM
                 Key: HIVE-22037
                 URL: https://issues.apache.org/jira/browse/HIVE-22037
             Project: Hive
          Issue Type: Improvement
          Components: HiveServer2
            Reporter: Barnabas Maidics
            Assignee: Barnabas Maidics


Currently, if HS2 runs into OOM issue, ThreadPoolExecutorWithOomHook kicks in 
and runs oomHook, which will stop HS2. Everything happens without logging. In 
the log, you can only see, that HS2 stopped. 

We should log the stacktrace.
