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

             Summary: Add long polling to asynchronous execution in HiveServer2
                 Key: HIVE-5217
                 URL: https://issues.apache.org/jira/browse/HIVE-5217
             Project: Hive
          Issue Type: Improvement
          Components: HiveServer2
    Affects Versions: 0.12.0
            Reporter: Vaibhav Gumashta
            Assignee: Vaibhav Gumashta


[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.
