      Hive 2.3.7

    Description

      I used JDBC to connect to HIVESERVER2 and got about 25,000 SQL statements as test data from the production environment to test parallel compilation. Then save the memory snapshot of hiveserver2. Then run the test again and save the memory snapshot. I found that the memory occupied became larger and the second time running was more slower.
