Xiaoxiang Yu updated KYLIN-4167:
--------------------------------
Description:
1. Currently, coordinator has too many responsibility, which violate single
responsibility principle, and it not easy for extension, a good separation of
responsibilities is a recommended way
2. Some cluster level operation has no atomicity guarantee, we should implement
then in idempotent way to achieve final consistency
3. Resubmit when job was discarded
4. Clarify overall design for realtime OLAP
> Refactor streaming coordinator
