Release Note:
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.
