Description

Taking latest code from master branch, I compiled Zeppelin using
mvn clean install -Pspark-1.6 -Dhadoop.version=2.5.0-cdh5.3.0 -Phadoop-2.4 -Pyarn -Pscala-2.11 -Pvendor-repo -Drat.skip -DskipTests -e
I'm using spark 1.6.2 also compiled using Scala 2.11
Using Java 1.7_67
When I try to create a spark (local[*]) interpreter, it gives me connection refused error. In the logs, I found this error:

Exception in thread "main" java.lang.NoSuchMethodError: scala.Predef$.$conforms()Lscala/Predef$$less$colon$less;

With spark compiled on scala 2.10, it is working fine.
