You can start HiveServer2, then submit queries to it using JDBC. If you open multiple sessions
using multiple threads, you will be able to submit queries in parallel, although the compilation
is still currently serialized.

Subject: Run multiple queries simultaneously

Hello,

I want to compare the running time of an query when run alone against the run time in presence
of other queries.

What is the ideal setup required to run this experiment ? Should I have two Hive CLI's open
and issue queries simultaneously ? How to script such experiment in Hive ?
