Here have a new Design: http://www.jianshu.com/p/ae7fdd4746f6
> Support dynamic allocation in Spark Streaming
> ---------------------------------------------

> Project: Spark
> Issue Type: Bug
> Components: Spark Core, Streaming

>
> Dynamic allocation is a feature that allows your cluster resources to scale
> up and down based on the workload. Currently it doesn't work well with Spark
> streaming because of several reasons:
> (1) Your executors may never be idle since they run something every N seconds
> (2) You should have at least one receiver running always
> (3) The existing heuristics don't take into account length of batch queue
> ...
> The goal of this JIRA is to provide better support for using dynamic
> allocation in streaming. A design doc will be posted shortly.
