spark pre-built binaries for 0.8.0

[Philip Ogren]

I have a question about the pre-built binary for 0.8.0 for CDH 4 listed 
here:

http://spark.incubator.apache.org/downloads.html
and linked here:

http://spark-project.org/download/spark-0.8.0-incubating-bin-cdh4.tgz

Should I expect that this release is compiled with YARN enabled (i.e. 
the SPARK_YARN property is set to true)?

Thanks,
Philip
