> Key: FLINK-29509
> URL: https://issues.apache.org/jira/browse/FLINK-29509
> Project: Flink
> Issue Type: Bug

> When we recover the `CheckpointCommittableManager` we ignore the subtaskId it is recovered on. [https://github.com/apache/flink/blob/d191bda7e63a2c12416cba56090e5cd75426079b/flink-streaming-java/src/main/java/org/apache/flink/streaming/runtime/operators/sink/committables/CheckpointCommittableManagerImpl.java#L58]
> This becomes a problem when a sink uses a post-commit topology because multiple committer operators might forward committable summaries coming from the same subtaskId.
>
> It should be possible to use the subtaskId already present in the `CommittableCollector` when creating the `CheckpointCommittableManager`s.
