             Summary: Verify optimized scheduler performance for large-scale jobs
                 Key: FLINK-23826
                 URL: https://issues.apache.org/jira/browse/FLINK-23826
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
    Affects Versions: 1.14.0
            Reporter: Zhu Zhu
             Fix For: 1.14.0


This ticket is used to verify the result of FLINK-21110.
It should check if large scale jobs' scheduling are working well and the scheduling performance, with a real job running on cluster. 

The conclusion should include:
1. time of job initialization on master (job received -> scheduling started)
2. time of job scheduling and deployment (scheduling started -> all tasks in INITIALIZATION)
3. time of job restarting on task failover (JM notified about task failure -> all tasks in INITIALIZATION again)
4. master heap memory required for large scale jobs
