Description
If you build with sbt (SPARK_WITH_YARN=true sbt/sbt package assembly) it will add the Yarn classes (YarnClientImpl) into the repl assembled jar ./repl/target/spark-repl-assembly-0.8.0-SNAPSHOT.jar , but if you build with mvn -Phadoop2-yarn package it doesn't add the Yarn class in the repl shaded jar (./repl-bin/target/spark-repl-bin-0.8.0-SNAPSHOT-shaded.jar)
We should keep these consistent. This matters for https://github.com/mesos/spark/pull/868 as it is relying on the YarnClientImpl being in the jar.
