    Alright, I am confused a little.
    
    @Pat, doest this patch break the build or it also occurs when packaging the
    master?
    
    @Dmitriy,
    My rationale is that, as it is suggested at
    
http://spark.apache.org/docs/latest/programming-guide.html#linking-with-spark,
    mahout, as a hadoop client, should add hadoop-client and spark_core as a
    dependency and then just work. The version of hadoop-client should support
    multiple hadoop versions since people might have hadoop clusters with
    different versions, from different vendors etc.
