> Kafka input operator has a separate thread to read from Kafka. Even if the Kafka reader
thread is not running, the operator will continue to run. 
> Ideally, following things needs to be done
> 1. More logging as to why the Kafka reader thread exited
> 2. If the Kafka reader thread gets killed either kill the container or retry with a new
thread.
