--------------------------------------

I left some more comments on reviewboard.

Are you planning to move the long polling timeout logic from SQLOperation.getState() to CLIService?

> [HIVE-4617|https://issues.apache.org/jira/browse/HIVE-4617] provides support for async
execution in HS2. The client gets an operation handle which it can poll to check on the operation
status. However, the polling frequency is entirely left to the client which can be resource
inefficient. Long polling will solve this, by blocking the client request to check the operation
status for a configurable amount of time (a new HS2 config) if the data is not available,
but responding immediately if the data is available.
