kafka+storm链接问题

[Lewis_Kong]

一个线上的简单的wordcount导致出错:

Unable to get offset lags for kafka. Reason: java.lang.NullPointerException at org.apache.storm.kafka.monitor.KafkaOffsetLagUtil.
getOffsetLags(KafkaOffsetLagUtil.java:272) at org.apache.storm.kafka.monitor.KafkaOffsetLagUtil.main(KafkaOffsetLagUtil.java:124)

    TopologyBuilder topologyBuilder = new TopologyBuilder();
        SpoutConfig spoutConfig = new SpoutConfig(
                new ZkHosts("kong1:2181,kong2:2181,kong3:2181,kong4:2181,kong5:2181"),
                "wordCount",
                "/wordCount",
                "wordCount");
        spoutConfig.startOffsetTime = kafka.api.OffsetRequest.LatestTime();
		topologyBuilder.setSpout("KafkaSpout",new KafkaSpout(spoutConfig),2);
        topologyBuilder.setBolt("bolt1",new MySplitBolt(),4).shuffleGrouping("KafkaSpout");
        topologyBuilder.setBolt("bolt2",new MyWordCountAndPrintBolt(),2).shuffleGrouping("bolt1");
