spark streaming printing no output

[Shushant Arora]

Hi

I am running a spark streaming application but on console nothing is
getting printed.

I am doing
1.bin/spark-shell --master clusterMgrUrl
2.import org.apache.spark.streaming.StreamingContext
import org.apache.spark.streaming.StreamingContext._
import org.apache.spark.streaming.dstream.DStream
import org.apache.spark.streaming.Duration
import org.apache.spark.streaming.Seconds
val ssc = new StreamingContext( sc, Seconds(1))
val lines = ssc.socketTextStream("hostname",7777)
lines.print()
ssc.start()
ssc.awaitTermination()

Jobs are getting created when I see webUI but nothing gets printed on
console.

I have started a nc script on hostname  port 7777 and can see messages
typed on this port from another console.



Please let me know If I am doing something wrong.
