[[email protected] 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.
[[email protected] logs]$ kafka-topics.sh --create --zookeeper datanode1:2181 --partitions 2 --replication-factor 3 --topic first
Error while executing topic command : Topic ‘first‘ already exists.
[2019-07-13 07:11:05,073] ERROR org.apache.kafka.common.errors.TopicExistsException: Topic ‘first‘ already exists.
(kafka.admin.TopicCommand$)
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。
