--------------------------------------

             Summary: Update the netty-3.x version in spark-assembly-*.jar
                 Key: SPARK-4738
                 URL: https://issues.apache.org/jira/browse/SPARK-4738
             Project: Spark
          Issue Type: Bug
          Components: Deploy
    Affects Versions: 1.1.0
            Reporter: Tobias Pfeiffer


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.
