> In AbstractCommitterOperator.endInput:
> Suppose the last checkpoint before endInput is 5. Flink Streaming Job calling order:
> 1. Accept elements from upstream prepareSnapshotPreBarrier(5)
> 2. this.snapshotState(5)
> 3. Accept elements from upstream endInput
> 4. this.endInput
> 5. this.notifyCheckpointComplete(5)
> So we should submit all the data in the endInput in order to avoid disordered commits.
