HI hamza !
if you want to see the result you can try programming your bolt to save
results emitted from the spout/bolt on a file .
as example :
PrinterBolt :
package storm.starter;
import backtype.storm.topology.BasicOutputCollector;
import backtype.storm.topology.OutputFieldsDeclarer;
import backtype.storm.topology.base.BaseBasicBolt;
import backtype.storm.tuple.Tuple;
import java.io.File;
import java.io.BufferedWriter;
import java.io.FileNotFoundException;
import java.io.FileWriter;
import java.io.IOException;
public class PrinterBolt extends BaseBasicBolt {
@Override
public void execute(Tuple tuple, BasicOutputCollector collector) {
try {
BufferedWriter output;
output = new BufferedWriter(new
FileWriter("/root/src/storm-starter/hh.txt", true));
output.newLine();
output.append(tuple.getString(0));
output.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
public void declareOutputFields(OutputFieldsDeclarer ofd) {
}
}
------------------------------------------------------------------------------------------------------------
then add your bolt to the main class topology
TopologyBuilder builder = new TopologyBuilder();
PrinterBolt P = new PrinterBolt();
builder.setSpout("word", new hhhhh( ), 1);
builder.setBolt("exclaim1", new ExclamationBolt(),
3).shuffleGrouping("word");
builder.setBolt("exclaim2", P , 2).shuffleGrouping("exclaim1");
