Description

It seems as if the version of akka-remote (2.2.3-shaded-protobuf) that is bundled in the spark-assembly-1.1.1-hadoop2.4.0.jar file pulls in an ancient version of netty, namely io.netty:netty:3.6.6.Final (using the package org.jboss.netty). This means that when using spark-submit, there will always be this netty version on the classpath before any versions added by the user. This may lead to issues with other packages that depend on newer versions and may fail with java.lang.NoSuchMethodError etc.(finagle-http in my case).

I wonder if it possible to manually include a newer netty version, like netty-3.8.0.Final.
