Hi Chanaka,

AFAIU, it's not possible for the same hive script to run in two different
nodes at the same time. Since the analyzer nodes are clustered and the
tasks are distributed among nodes. So, only one analyzer will run a
specific hive script at any given time.

By having a Hadoop cluster, you can improve the performance for analyzing
operations.

I hope this helps.

Thanks!

Best Regards,
