Streaming from HDFS folder - scala

Question

I am trying to implement a scala + spark solution to streaming a word count information from new values from a HDFS folder, like this:
import org.apache.spark.SparkConf
import org.apache.spark.streaming.{Seconds, StreamingContext}
import StreamingContext._
import org.apache.hadoop.conf._
import org.apache.hadoop.fs._
object HdfsWordCount {
def main(args: Array[String]) {
if (args.length < 1) {
System.err.println("Usage: HdfsWordCount <directory>")
System.exit(1)
}
val sparkConf = new SparkConf().setAppName("HdfsWordCount")
// Create the context
val ssc = new StreamingContext(sparkConf, Seconds(2))
// Create the FileInputDStream on the directory and use the
// stream to count words in new files created
val lines = ssc.textFileStream(args(0))
val words = lines.flatMap(_.split(" "))
val wordCounts = words.map(x => (x, 1)).reduceByKey(_ + _)
wordCounts.print()
ssc.start()
ssc.awaitTermination()
}
}
I tried with spark-shell running HdfsWordCount.main(Array('hdfs:///user/cloudera/sparkStreaming/'))
and it just give a | and leaving me to type. Am I doing something wrong?
