>             Project: Samza
>          Issue Type: Bug
>            Reporter: Prateek Maheshwari
>            Assignee: Prateek Maheshwari
>            Priority: Major
> Make StreamPartitionCountMonitor less aggressive and only restart (stateless) 
> or shut down (stateful) the job if partition count increases.
> In some versions of KafkaConsumer, partitionFor(topic) can return a count 
> lower than the configured number of partitions if the broker it asks has 
> recently restarted.
> The only downside of not restarting the job on partition count decreases is 
> that some containers may be idle.
