sachin aggarwal commented on SPARK-13069:
-----------------------------------------
As of Spark 2.0 (not yet released), Spark does not use Akka any more.
See https://issues.apache.org/jira/browse/SPARK-5293
can you check with latest 2.0 build, to see if similar problem exists.
> ActorHelper is not throttled by rate limiter

>
> Key: SPARK-13069
> URL: https://issues.apache.org/jira/browse/SPARK-13069
> Project: Spark
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 1.6.0
> Reporter: Lin Zhao
>
> The rate an actor receiver sends data to spark is not limited by maxRate or
> back pressure. Spark would control how fast it writes the data to block
> manager, but the receiver actor sends events asynchronously and would fill
> out akka mailbox with millions of events until memory runs out.
