同事新搭建了一个kafka集群，在创建topic的时候遇到错误：

执行：./kafka-topics.sh --zookeeper linux1:2181 --create --topic test --replication-factor 1 --partitions 1

报错：

百度了一下发现是因为没有指定kafka在zookeeper上的根目录。不知道是不是版本的问题，我在用0.9的时候没有出现这种问题，但是用0.8的时候就出现了。

修改为：./kafka-topics.sh --zookeeper linux1:2181/kafka --create --topic test --replication-factor 1 --partitions 1

创建成功
