Thanks Matthew. The wiki page http://wiki.apache.org/hadoop/Hive/HiveServer 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.
