--------------------------------------
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.
