> 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
> (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.
