> Project: Apache Lens
> Issue Type: Improvement
> Components: server
> Reporter: Amareshwari Sriramadasu
> Assignee: Amareshwari Sriramadasu

>
> We need to isolate query submitters for each driver to be different. We have
> seen scenarios where hive submission takes time and other interactive queries
> on jdbc are queued because querysubmitter was busy.
> Also, each driver can have a pool of submitters - which should benefit
> interactive queries with immediate submissions, especially the ones submitted
> on EXECUTE_WITH_TIMEOUT
