> Created the following application to reproduce this issue.
> Application has the following DAG:
>    KafkaSinglePortStringInputOperator(Input) -> ConsoleOutputOperator(Output)
>    
>    I launched the application with below configuration:
> Kafka topic created with single partition and replication factor as 1.
> Partition Strategy: ONE_TO_ONE
>    Launched the application successfully. After some time, I increased the topic partitions to 2. After re-partition, the window of down stream operator is not moving. By looking into the app Physical DAG, it looks like there is an issue in construction of Physical DAG after re-partition.
