> 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: 1.5.0, 1.6.0
> Reporter: Stefan Richter
> Assignee: Stefan Richter
> Priority: Major
> Labels: pull-request-available
>
> 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.
