Kafka学习之Replication tools之Create Topic Tool

原文链接：https://cwiki.apache.org/confluence/display/KAFKA/Replication+tools#Replicationtools-3.ListTopicTool

此工具能干啥？

如果设置auto.create.topics.enable为true，则Kafka会默认自动创建topic。会使用默认的partition数量，replication factor和Kafka的默认schema来做replica assignment。有时候我们想自定义一下，此工具帮助我们使用指定的partition数量，replication factor和replica assignment列表来创建一个topic。

如何使用?
