[jira] [Created] (FLINK-29509) Set correct subtaskId during recovery of committables

Fabian Paul created FLINK-29509:
-----------------------------------

             Summary: Set correct subtaskId during recovery of committables
                 Key: FLINK-29509
                 URL: https://issues.apache.org/jira/browse/FLINK-29509
             Project: Flink
          Issue Type: Bug
          Components: Connectors / Common
    Affects Versions: 1.15.2, 1.17.0, 1.16.1
            Reporter: Fabian Paul


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.
