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

After overcoming this with symlinks and setting SPARK_HOME I hit another issue:
Caused by: java.lang.NoSuchMethodError: io.netty.channel.DefaultFileRegion.<init>(Ljava/io/File;JJ)V at org.apache.spark.network.buffer.FileSegmentManagedBuffer.convertToNetty(FileSegmentManagedBuffer.java:133) at org.apache.spark.network.protocol.MessageEncoder.encode(MessageEncoder.java:58) at org.apache.spark.network.protocol.MessageEncoder.encode(MessageEncoder.java:33) at io.netty.handler.codec.MessageToMessageEncoder.write(MessageToMessageEncoder.java:89)
I believe this will be an incompatibility between netty-all versions required by hadoop and spark..
