Looks the message is consumed by the another console?( can see messages typed
on this port from another console.)

Subject: Re: spark streaming printing no output
When I launched spark-shell using, spark-shell ---master local[2].
Same behaviour, no output on console but only timestamps.
When I did, lines.saveAsTextFiles("hdfslocation",suffix);
I get empty files of 0 bytes on hdfs

Just make sure you have atleast 2 cores available for processing. You can try
launching it in local[2] and make sure its working fine.
Thanks

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.
