> support customized akka system for actor-based receiver
> -------------------------------------------------------
>                 Key: SPARK-6422
>                 URL:
>             Project: Spark
>          Issue Type: Improvement
>          Components: Streaming
>    Affects Versions: 1.4.0
>            Reporter: Nan Zhu
> To disable the Akka's fault detection system, we currently set large default values for
Akka' transport failure detector threshold and heartbeat interval, and discourage users to
customize these values..
> Meanwhile, we are trying to eliminate the dependency to Akka, e.g. we are trying to implement
a general RPC interface (, etc.
> Based on the above facts, enabling a customized Akka system for actor-based receiver
has two benefits: 1) users can easily set values related to failure detector which are more
practical in general Akka usage scenario; 2) reduce the dependency level to Akka, (in future,
we can even move Actor-based receiver to external project)
