1 启动advertised.listeners配置异常:

java.lang.IllegalArgumentException: requirement failed: advertised.listeners cannot use the nonroutable meta-address 0.0.0.0. Use a routable IP address.
    at scala.Predef$.require(Predef.scala:277)
    at kafka.server.KafkaConfig.validateValues(KafkaConfig.scala:1203)
    at kafka.server.KafkaConfig.<init>(KafkaConfig.scala:1170)
    at kafka.server.KafkaConfig$.fromProps(KafkaConfig.scala:881)
    at kafka.server.KafkaConfig$.fromProps(KafkaConfig.scala:878)
    at kafka.server.KafkaServerStartable$.fromProps(KafkaServerStartable.scala:28)
    at kafka.Kafka$.main(Kafka.scala:82)
    at kafka.Kafka.main(Kafka.scala)

1.1 解决方法：修改server.properties

advertised.listeners=PLAINTEXT://{ip}:9092  # ip可以内网、外网ip、127.0.0.1 或域名

1.2 解析：

server.properties中有两个listeners。 listeners：启动kafka服务监听的ip和端口，可以监听内网ip和0.0.0.0(不能为外网ip)，默认为java.net.InetAddress.getCanonicalHostName()获取的ip。advertised.listeners：生产者和消费者连接的地址，kafka会把该地址注册到zookeeper中，所以只能为除0.0.0.0之外的合法ip或域名 ，默认和listeners的配置一致。

2 启动PrintGCDateStamps异常

[0.004s][warning][gc] -Xloggc is deprecated. Will use -Xlog:gc:/data/service/kafka_2.11-0.11.0.2/bin/../logs/kafkaServer-gc.log instead.
Unrecognized VM option 'PrintGCDateStamps'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

2.1 解决方法: 更换jdk1.8.x版本或者使用>=kafka1.0.x的版本。

2.2 解析：

只有在jdk1.9并且kafka版本在1.0.x之前的版本才会出现。

3 生成者发送message失败或消费者不能消费(kafka1.0.1)

#(java)org.apache.kafka警告
Connection to node 0 could not be established. Broker may not be available.


# (nodejs) kafka-node异常 (执行producer.send后的异常)
{ TimeoutError: Request timed out after 30000ms
    at new TimeoutError (D:\project\node\kafka-test\src\node_modules\kafka-node\lib\errors\TimeoutError.js:6:9)
    at Timeout.setTimeout [as _onTimeout] (D:\project\node\kafka-test\src\node_modules\kafka-node\lib\kafkaClient.js:737:14)

    at tryOnTimeout (timers.js:304:5)
    at Timer.listOnTimeout (timers.js:264:5) message: 'Request timed out after 30000ms' }

3.1 解决方法: 检查advertised.listeners的配置（如果有多个Broker可根据java版本的对应的node号检查配置），判断当前的网络是否可以连接到地址(telnet等)

4 partitions配置的值过小造成错误(kafka1.0.1)

#(java)org.apache.kafka(执行producer.send)
Exception in thread "main" org.apache.kafka.common.KafkaException: Invalid partition given with record: 1 is not in the range [0...1).

    at Socket.Readable.push (_stream_readable.js:209:10) message: 'Could not find the leader' }

4.1 解决方法: 修改num.partitions的值，partitions在是在创建topic的时候默认创建的partitions节点的个数，只对新创建的topic生效，所有尽量在项目规划时候定一个合理的值。也可以通过命令行动态扩容()

./bin/kafka-topics.sh --zookeeper  localhost:2181 --alter --partitions 2 --topic  foo
