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.
This is the first time I have submitted an issue. If there is any incomplete
description, please point it out. If the format of the issue is incorrect,
please help me modify it, thank you
