1996fanrui opened a new pull request, #801:
URL: https://github.com/apache/flink-kubernetes-operator/pull/801
## What is the purpose of the change
Currently, the autoscaler will scale a job when the JobStatus is RUNNING.
But the JobStatus will be RUNNING once job starts schedule, so it doesn't mean
all tasks are running. Especially, when the resource isn't enough or job
recovers from large state.
The autoscaler will throw exception and generate the AutoscalerError event
when tasks are not ready. Also, we don't need to scale it when some tasks are
not ready.
## Brief change log
- [FLINK-34906] Only scale when all tasks are running
- Solution: we only scale job that all tasks are running(some of tasks may
be finished).
We can know how many tasks are running from `JobDetailsInfo`:
