> Project: Flink
> Issue Type: Bug
> Components: Kubernetes Operator
> Affects Versions: kubernetes-operator-1.10.0
> Environment: I've attached the flinkdeployment CR I used to locally
> replicate.
> Reporter: Luca Castelli
> Assignee: Luca Castelli
> Priority: Minor
> Labels: pull-request-available
> Fix For: kubernetes-operator-1.12.0
>
> Attachments: operator-log-batch-job.log, test-batch-job.yaml
>
>
> The root error (full logs attached):
>
> {code:java}
> Caused by: org.apache.flink.runtime.rest.util.RestClientException:
> [org.apache.flink.runtime.rest.handler.RestHandlerException: Checkpointing
> has not been enabled.

> the operator successfully connects to the Flink REST API
> # It tries to get checkpoint statistics via CheckpointingStatisticsHandler,
> but the handler throws an error because checkpointing is not enabled. This is
