Are you wrong
zookeeperPath , // the root path in Zookeeper for the spout to store the
consumer offsets
Is for you KafkaSpout find information about broker meta information (
topics, partitions)
You have to override
SpoutConfig spoutconfig = new SpoutConfig(zkhost, "bid_history",
"/brokers", "kafka-spout");
spoutconfig.zkServers
spoutconfig.zkPort
Take a look a KafkaSpout.class and do a debug mode in this part.
73 Map stateConf = new HashMap(conf);
74 List<String> zkServers = _spoutConfig.zkServers;
if (zkServers == null) {
zkServers = (List<String>)
conf.get(Config.STORM_ZOOKEEPER_SERVERS);
}
Integer zkPort = _spoutConfig.zkPort;
if (zkPort == null) {
zkPort = ((Number)
conf.get(Config.STORM_ZOOKEEPER_PORT)).intValue();
}
