Matthias Pohl updated FLINK-25267:
----------------------------------
Component/s: Runtime / Checkpointing
> Unable to (always) recover using checkpoint in HA setup (both Zookeeper and
> Kubernetes)
> ---------------------------------------------------------------------------------------
>
> Key: FLINK-25267
> URL: https://issues.apache.org/jira/browse/FLINK-25267
> Project: Flink
> Issue Type: Bug
> Components: Deployment / Kubernetes, Runtime / Checkpointing,
> Stateful Functions
> Affects Versions: 1.12.1, statefun-3.0.0, statefun-3.1.0, 1.13.2
> Environment: MacOS 11.6, minikube v1.23.2, tried with both Stateful
> Functions 3.0.0 and Stateful Functions 3.1.0
> Reporter: Kerem Ulutaş
> Priority: Major
>
> My Stateful Functions job is running on Kubernetes (minikube on my local env)
> and has these settings:
> * Using StateFun v3.1.0
> * Checkpoints are stored on HDFS (state.checkpoint-storage: filesystem)
> * Checkpointing mode is EXACTLY_ONCE
> * State backend is rocksdb and incremental checkpointing is enabled
> When I kill the jobmanager (master) pod, minikube starts another pod and this
> new pod fails when it tries to load last checkpoint:
> {code:java}
