storm 集成kafka时遇见的问题

一、KafkaSpout 引起的 log4j 的问题

问题描述：

SLF4J: Detected both log4j-over-slf4j.jar AND slf4j-log4j12.jar on the class path, preempting StackOverflowError.
SLF4J: See also http://www.slf4j.org/codes.html#log4jDelegationLoop for more details.

原因：

KafkaSpout

 代码里（

storm.kafka.KafkaSpout

）使用了
slf4j 的包，而 Kafka 系统本身（

kafka.consumer.SimpleConsumer

）却使用了
apache 的包，

解决办法：在依赖定义中去除问题依赖包

<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka_2.10</artifactId>
<version>0.10.1.1</version>
<exclusions>

二、Kafka-client报错

原因：org.apache.kafka.common.network.NetworkSend 是一个Kafka客户端库，kafka 0.9以前，首先初始化这个类，pom.xml中未显示的声明Kafka-clients，故导致错误。

解决办法：加入Kafka-clients依赖

<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-clients</artifactId>
<version>0.10.0.1</version>
</dependency>
