--------------------------------
shall we make this JIRA as an umbrella task, so that the other JIRAs like
SPARK-5214 can be associated to here?
> Enable Spark user applications to use different versions of Akka
> ----------------------------------------------------------------
>
> Key: SPARK-5293
> URL: https://issues.apache.org/jira/browse/SPARK-5293
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 1.3.0
> Reporter: Reynold Xin
>
> A lot of Spark user applications are using (or want to use) Akka. Akka as a
> whole can contribute great architectural simplicity and uniformity. However,
> because Spark depends on Akka, it is not possible for users to rely on
> different versions, and we have received many requests in the past asking for
> help about this specific issue. For example, Spark Streaming might be used as
> the receiver of Akka messages - but our dependency on Akka requires the
> upstream Akka actors to also use the identical version of Akka.
> Since our usage of Akka is limited (mainly for RPC and single-threaded event
> loop), we can replace it with alternative RPC implementations and a common
> event loop in Spark.
