Josh Rosen resolved SPARK-4738.
-------------------------------
Resolution: Incomplete
Resolving as "Incomplete" since this an old issue and it doesn't look like
there's any action to take here. In newer Spark versions, you should be able to
use the various user-classpath-first configurationst o work around this.
> 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: Improvement
> Components: Deploy
> Affects Versions: 1.1.0
> Reporter: Tobias Pfeiffer
> Priority: Minor
>
> 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.
