> Project: Spark
> Issue Type: Improvement

> Environment: Ubantu

> I am analyzing streaming input from kafka. For example I calculate average use of a resource over a period of time. It works great.
> The problem is that if I need to make a change to the analysis, for example change from average to max or add another item to the list of item to analyze then I have to stop the spark application and restart it (at least I have to stop the streaming context and restart the context).
> I would think it will be a great addition if spark can add new streams on the fly or make modifications on the existing stream
