> Assignee: Adam Szita
>
> When running tests in yarn-client mode that were built with Spark 2 I'm
> getting the following exception:
> {code}
> Caused by: java.lang.IllegalStateException: Library directory
> '...../pig/assembly/target/scala-2.11/jars' does not exist; make sure Spark
> is built.

> {code}
> After overcoming this with symlinks and setting SPARK_HOME I hit another
> issue:
> {code}
> Caused by: java.lang.NoSuchMethodError:
> io.netty.channel.DefaultFileRegion.<init>(Ljava/io/File;JJ)V

> I believe this will be an incompatibility between netty-all versions required
> by hadoop and spark..
