> 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.
