1.安装kafka的过程出现两个问题
1）错误: 找不到或无法加载主类 kafka.Kafka
原因：
2） ERROR Invalid config, exiting abnormally (org.apache.zookeeper.server.quorum.QuorumPeerMain)
org.apache.zookeeper.server.quorum.QuorumPeerConfig$ConfigException: Error processing config/zookeeper.properti
原因：启动时候 在 kafka的 bin目录，通过 ./zookeeper-server-start.sh config/zookeeper.properties & 启动的，应该是在 kafak的目录，通过bin/zookeeper-server-start.sh config/zookeeper.properties & 来启动
3）ERROR org.apache.kafka.common.errors.InvalidReplicationFactorException: replication factor: 1 larger than available brokers: 0
需要启动broker:
bin/zookeeper-server-start.sh config/zookeeper.properties
bin/kafka-server-start.sh config/server.properties原文：http://www.cnblogs.com/thinkingandworkinghard/p/6113069.html
