[ERROR][default/flink-example-statemachine] Checkpoint triggering task Source:
Custom Source (1/2) of job 00000000000000000000000000000000 is not being

tasks are currently running. {code}
How to reproduce?
Update arbitrary fields(e.g. parallelism) along with
{{{}savepointTriggerNonce{}}}.
The root cause might be the running state return by
{{ClusterClient#listJobs()}} does not mean all the tasks are running.
