-------------------------------------------
I've created FLINK-26079 for disabling support for recovery in `CLAIM` mode.
> Restoring from non-changelog checkpoint with changelog state-backend enabled
> in CLAIM mode discards state in use

> Key: FLINK-25872
> URL: https://issues.apache.org/jira/browse/FLINK-25872
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing, Runtime / State Backends
> Reporter: Yun Tang
> Priority: Blocker
> Fix For: 1.15.0
>
>
> If we restore from checkpoint with changelog state-backend enabled in
> snapshot CLAIM mode, the restored checkpoint would be discarded on subsume.
> This invalidates newer/active checkpoints because their materialized part is
> discarded (for incremental wrapped checkpoints, their private state is
> discarded). This bug is like FLINK-25478.
