[jira] [Created] (FLINK-10377) Remove precondition in TwoPhaseCommitSinkFunction.notifyCheckpointComplete

Stefan Richter created FLINK-10377:
--------------------------------------

             Summary: Remove precondition in TwoPhaseCommitSinkFunction.notifyCheckpointComplete
                 Key: FLINK-10377
                 URL: https://issues.apache.org/jira/browse/FLINK-10377
             Project: Flink
          Issue Type: Bug
          Components: Streaming Connectors
    Affects Versions: 1.6.0, 1.5.0
            Reporter: Stefan Richter
            Assignee: Stefan Richter


The precondition {{checkState(pendingTransactionIterator.hasNext(), "checkpoint completed, but no transaction pending");}} in {{TwoPhaseCommitSinkFunction.notifyCheckpointComplete()}} seems to strict, because checkpoints can overtake checkpoints and will fail the precondition. In this case the commit was already performed by the first notification and subsumes the late checkpoint. I think the check can be removed.
