Hi Yangze, Thanks a lot for your reply. References are very helpful! Another quick question. Reference 1 can start a standalone cluster (session Mode). That cluster has a jobManager. I can submit job to run. How about taskManger? Do I need to manually start multiple taskManagers? Is there a complete example to show the process?
