Josh Rosen resolved SPARK-5487.
-------------------------------
    Resolution: Won't Fix

Resolving as "Won't Fix" for now, since this is no longer needed now that 
SPARK-7042 has been merged. If you think that this Dockerfile should live 
somewhere other than JIRA, please open a pull request against the appropriate 
Spark maintenance branch. Thanks!

> Dockerfile to build spark's custom akka.

>                 Key: SPARK-5487
>                 URL: https://issues.apache.org/jira/browse/SPARK-5487
>             Project: Spark
>          Issue Type: Improvement
>          Components: Build
>    Affects Versions: 1.2.0
>            Reporter: jay vyas
>            Priority: Minor

> Building spark's custom shaed akka version is tricky.  The code is in 
> https://github.com/pwendell/akka/ (branch = 2.2.3-shaded-proto) , however, 
> when attempting to build, I receive some strange errors.
> I've attempted to fork off of a Dockerfile for {{SBT 0.12.4}}, which I'll 
> attach in a snippet just as an example of what we might want to facilitate 
> building the spark specific akka until SPARK-5293 is completed.
