STORM配置TOPOLOGY问题

最初的错误：

DynamicBrokersReader [ERROR] Node /brokers/ids/0 does not exist

设置：

BrokerHosts brokerHosts = new ZkHosts(zks, "/kafka/brokers");

然后就是如下错误：

2016-04-13T15:07:10.657+0800 b.s.util [ERROR] Async loop died!java.lang.RuntimeException: java.lang.RuntimeException: org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /kafka/brokers/topics/testtopic/partitions    at storm.kafka.DynamicBrokersReader.getBrokerInfo(DynamicBrokersReader.java:81) ~[storm-kafka-0.9.6.jar:0.9.6]    at storm.kafka.trident.ZkBrokerReader.(ZkBrokerReader.java:42) ~[storm-kafka-0.9.6.jar:0.9.6]    at storm.kafka.KafkaUtils.makeBrokerReader(KafkaUtils.java:57) ~[storm-kafka-0.9.6.jar:0.9.6]    at storm.kafka.KafkaSpout.open(KafkaSpout.java:87) ~[storm-kafka-0.9.6.jar:0.9.6]    at backtype.storm.daemon.executor$fn__3371$fn__3386.invoke(executor.clj:529) ~[storm-core-0.9.6.jar:0.9.6]    at backtype.storm.util$async_loop$fn__460.invoke(util.clj:461) ~[storm-core-0.9.6.jar:0.9.6]    at clojure.lang.AFn.run(AFn.java:24) [clojure-1.5.1.jar:na]    at java.lang.Thread.run(Thread.java:662) [na:1.6.0_38]Caused by: java.lang.RuntimeException: org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /kafka/brokers/topics/testtopic/partitions    at storm.kafka.DynamicBrokersReader.getNumPartitions(DynamicBrokersReader.java:94) ~[storm-kafka-0.9.6.jar:0.9.6]    at storm.kafka.DynamicBrokersReader.getBrokerInfo(DynamicBrokersReader.java:65) ~[storm-kafka-0.9.6.jar:0.9.6]    ... 7 common frames omitted

分析发现，在

DynamicBrokersReader类中虽然读取的是zkPath但是，前面的连接地址已经有了前缀地址，所以后面不用再加上

去掉了还是报最初的错误，再分析

在zkCli.sh进入zookeeper后检查，确实没有0，只有1，2，3这是在配置kafka时就定义的id了

在kafka/config/server.properties中配置broker.id = 0（其他机器顺序配置），重启，问题解决！
