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
