Even if it is single threaded it certainly seems to support multiple connections.

We run 5 workers all connected at the same time executing a different query each ( with a different connection per worker).

Hope that helps

Thanks Matthew. The wiki page says
its single threaded. I have a queue of queries which gets added dynamically all
the time. By the time I run 1 query using 1 JDBC connection, the queue gets
added more queries and builds up a backlog. So, I was that's why I was wondering
whether I can run two or more instances to avoid having a big backlog in queue.

Why would you want to run two? I think it is multithreaded, so you can query it
from two different connections

I have one instance of HIVE JDBC server running on port 10000. Can I run

instance on different port ? Would it cause a concurrency issue on the
underlying data warehouse files ? Please clarify.
