[Eric Kimbrel]

i've recently updated to the latest code on spark hub and can no longer create a new SparkContext

using SNAPSHOT-0.7.0

 sc = new SparkContext("local","some_name")

java.lang.NoSuchMethodError: scala.Predef$.augmentString(Ljava/lang/String;)Lscala/collection/immutable/StringOps;

It sounds like you're using a different version of Scala, or have somehow not linked to Spark correctly. However, don't bother trying to use the master branch. There's nothing new in it except a version number right now. Stick with the 0.6 release from http://www.spark-project.org/downloads.html.

looks like i was using scala 2.10 instead 2.9.2  I'll see if that will fix it. thanks.
