[hadoop@datanode3 logs]$ kafka-topics.sh –delete –zookeeper datanode1:2181 –topic first
Topic first is marked for deletion.
Note: This will have no impact if delete.topic.enable is not set to true.
[hadoop@datanode3 logs]$ kafka-topics.sh –create –zookeeper datanode1:2181 –partitions 2 –replication-factor 3 –topic first
Error while executing topic command : Topic ‘first’ already exists.

报错原因是我当时kafka-console-producer.sh和kafka-console-consumer.sh都还在运行，删除只删除了部分patition
后来关掉kafka-console-producer.sh和kafka-console-consumer.sh进程后，再删除，再创建同名的topic就不报错了。
