Subject Re: Need help on kafka-storm
Date Tue, 02 Dec 2014 03:20:13 GMT

Ok from the earlier logs it looks like your tuples are being timed out
and getting replayed. In your PrintBolt.execute do collector.ack(tuple)
public class PrintBolt extends BaseRichBolt { private static final long
serialVersionUID = 1L; private OutputCollector collector;

public void execute(Tuple tuple) { System.out.println("message " +
tuple.getValues()); collector.ack(tuple); } public void prepare(Map
arg0, TopologyContext arg1, OutputCollector arg2) { this.collector =
arg2; } public void declareOutputFields(OutputFieldsDeclarer arg0) { } }
