============================ Test Spark=============================

scala> val rdd=sc.textFile("hdfs://hadoop-spark.dragon.org:8020/user/hadoop/data/wc.input")

scala> rdd.cache()

scala> val wordcount=rdd.flatMap(_.split(" ")).map(x=>(x,1)).reduceByKey(_+_)

scala> wordcount.take(10)

scala> val wordsort=wordcount.map(x=>(x._2,x._1)).sortByKey(false).map(x=>(x._2,x._1))

scala> wordsort.take(10)
