> Issue Type: Bug
> Components: runner-spark
> Affects Versions: 0.4.0
> Reporter: Kobi Salant
> Assignee: Stas Levin
>
> Spark Runner streaming batch duration does not include duration of reading
> from source this is because we perform rdd.count in SparkUnboundedSourcewhich
> that invokes a regular spark job outside the streaming context.
> We do it for reporting the batch size both for UI and back pressure
