> Key: FLINK-25395
> URL: https://issues.apache.org/jira/browse/FLINK-25395
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing, Runtime / State Backends
> Affects Versions: 1.15.0
> Reporter: Roman Khachatryan
> Assignee: Roman Khachatryan
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 1.15.0

>
> Extracting from FLINK-25185 discussion
> On checkpoint abortion or any failure in AsyncCheckpointRunnable,
> it discards the state, in particular shared (incremental) state.
> Since FLINK-24611, this creates a problem because shared state can be re-used
> for future checkpoints.
>
> A similar case is in PeriodicMaterializationManager (uploaded SST files will
> be deleted on failure without notifying the wrapped RocksDB state backend).
>
> Symptom of this failure is a following exception during recovery:
> {noformat}
> Caused by: java.io.FileNotFoundException:
> /tmp/junit3146957979516280339/junit1602669867129285236/d6a6dbdd-3fd7-4786-9dc1-9ccc161740da
