Thank you Harsha for your response.
I'm just printing the messages in printer bolt.
Please find below printer blot code
*public class PrintBolt extends BaseRichBolt { private static final
long serialVersionUID = 1L; public void execute(Tuple tuple)
{ System.out.println("message " + tuple.getValues()); } public
void prepare(Map arg0, TopologyContext arg1, OutputCollector arg2) { }
public void declareOutputFields(OutputFieldsDeclarer arg0) { }}*
Regards,
Rajesh
