Topic is MarkedForDeletion , how to force topic deletion without topic aggressive removal from disk-CodePudding

We have kafka broker cluster version - 2.7 , we have 3 brokers machines

We removed the following topic , by following cli

bin/kafka-topics.sh --delete --zookeeper zoo01:2181 --topic my_first_car

After 1 day

we still see the topics on kafka disk , and also from following command

kafka-topics.sh --zookeeper zoo01:2181 --describe 
Topic: my_first_car   PartitionCount: 200     ReplicationFactor: 1    Configs: segment.bytes=1073741824,retention.bytes=7434770380    MarkedForDeletion: true
        Topic: my_first_car   Partition: 0    Leader: none    Replicas: 1001  Isr: 1001       MarkedForDeletion: true
        Topic: my_first_car   Partition: 1    Leader: none    Replicas: 1002  Isr: 1002       MarkedForDeletion: true
        Topic: my_first_car   Partition: 2    Leader: none    Replicas: 1003  Isr: 1003       MarkedForDeletion: true
        Topic: my_first_car   Partition: 3    Leader: none    Replicas: 1001  Isr: 1001       MarkedForDeletion: true
        Topic: my_first_car   Partition: 4    Leader: none    Replicas: 1002  Isr: 1002       MarkedForDeletion: true
        Topic: my_first_car   Partition: 5    Leader: none    Replicas: 1003  Isr: 1003       MarkedForDeletion: true
        Topic: my_first_car   Partition: 6    Leader: none    Replicas: 1001  Isr: 1001       MarkedForDeletion: true
        Topic: my_first_car   Partition: 7    Leader: none    Replicas: 1002  Isr: 1002       MarkedForDeletion: true

We also notice that topics is exist on zookeeper under /topics

So in order to try to complete delete this topic we restart all Kafka broker machines , but this isn't help

What are the next steps to delete the topic - my_first_car

It is ridiculous , that Kafka provide cli to delete topic , but actually topic stay on Kafka disk

Note - the last thing that we want is to delete the topic from the disks and from the zookeeper , but this is the ugly way

CodePudding user response：

The issue appears to be Leader: none. Not sure how the ISR list is updated with valid values, but there seems to be some corruption between Zookeeper and the Controller node such that the Leader is unknown, so the topic data cannot be resolved in order to be deleted.
