Sean Owen resolved SPARK-12697.
-------------------------------
Resolution: Won't Fix
> Allow adding new streams without stopping Spark streaming context
> -----------------------------------------------------------------
>
> Key: SPARK-12697
> URL: https://issues.apache.org/jira/browse/SPARK-12697
> Project: Spark
> Issue Type: Improvement
> Components: Streaming
> Affects Versions: 1.6.0
> Environment: Ubantu
> Reporter: Johny Mathew
> Labels: features
>
> 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
