Hi,
We are running Flink in K8S. We used
https://ci.apache.org/projects/flink/flink-docs-release-1.10/ops/jobmanager_high_availability.html
to set high availability. We set max number of retries for a task to 2.
After task fails twice and then the job manager fails. This is expected. But it
is removing checkpoint from the zookeeper. As a result on the restart it is not
consuming from the previous checkpoint. We are losing the data.
