-------------------------------
Summary: jobRunningTs should be the timestamp that all tasks are
running
Key: FLINK-34907
URL: https://issues.apache.org/jira/browse/FLINK-34907
Project: Flink
Issue Type: Improvement
Components: Autoscaler
Reporter: Rui Fan
Assignee: Rui Fan
Fix For: kubernetes-operator-1.9.0
Currently, we consider the timestamp that JobStatus is changed to RUNNING as
jobRunningTs. But the JobStatus will be RUNNING once job starts schedule, so it
doesn't mean all tasks are running.
It will let the isStabilizing or estimating restart time are not accurate.
Solution: jobRunningTs should be the timestamp that all tasks are running.
It can be got from SubtasksTimesHeaders rest api.
