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.
