    Description

      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.
