and the job manager is created successfully but the task manager pod is not
created, there's no error log in flink operator and job manager.

Follow picture is pods list in my k8s environment.



 

And the same config using application mode, the job can create successfully.

 

It troubles me serveral days. Can someone help me ? Thank you.
