Review comment:
       Are we targeting specific queries like auto-gather background stats 
threads & compaction ? why are we not providing a config to toggle sync/async 
delete ?

> In cloud environment, scratchdir cleaning at the end of the query may take 
> long time. This causes client to hang up to 1 minute even after the results 
> were streamed back. During this time client just waits for cleanup to finish. 
> Cleanup can take place in the background in HiveServer.
