> Flink HA persisted canceled job in Zookeeper, which makes HA mode quite
> fragile. In case JM get restarted, it tries to recover canceled job and after
> some time fails completely being not able to recover it.

> How to reproduce:
> # Have Flink HA 1.6 cluster
> # Cancel a running flink job
> # Observe that flink didn't remove ZK metadata.
