Running Hive Queries in Parallel?

Hello,

When I execute multiple queries in Hive, the mapred tasks are queued up and
executed one by one. Is there are way I could set Hive or Hadoop to execute
mapred tasks in parallel?

I am running on Hive 0.4.1 and Hadoop 0.20

Tx!

Found *hive*.*exec*.*parallel!!!*
How can I set to to be 'true' by default?

Thanks!
