> 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
