Hi Van
In my test, JDBC supported about 25 connections in the same time without delay.
If more connections , it will line up and timeout exception will happen.

Thanks for the response.
I see. Would JDBC then be a better option for concurrent connections?
I am not aware of the implementation of hive-JDBC so wonder if it
support multiple connections?
Any idea?
