I am not sure the exception is due to scala version mismatch (does this happen when you run the client on the master machine ?). Supporting scala-2.11 is a necessity though so we can keep this issue open to track that.
does this happen when you run the client on the master machine ?
No, @shivaram, it doesn't. Running the driver program directly on the master appears to work fine.

It appears as though branch-2.0 still uses scala 2.10, as evidenced from these lines from the log (produced from a
spark-ec2 ... launch ...
invocation):I'm still trying to effort whether this is the root cause for the errors I'm seeing when attempting to
run-example --master ... SparkPi 10
, which look like the following (notejava.io.InvalidClassException
messages below).In any case, however, it still seems as though scala 2.11 should be the version installed on master & slave.
