@Technoboy- This maybe should not skip the system topic check here, I test it. There maybe problems. 1. Deleting a namespace may return 500 ``` ➜ bin git:(master) ✗ ./pulsar-admin namespaces delete sample/ns1 2021-12-16T16:51:07,550+0800 [AsyncHttpClient-7-1] WARN org.apache.pulsar.client.admin.internal.BaseResource - [http://localhost:8080/admin/v2/namespaces/sample/ns1?force=false] Failed to perform http delete request: javax.ws.rs.InternalServerErrorException: HTTP 500 Internal Server Error HTTP 500 Internal Server Error ``` 2. Can still find the namespace after deleting it ``` ➜ bin git:(master) ✗ ./pulsar-admin topics list sample/ns1 persistent://sample/ns1/__change_events ``` 3. Broker maybe print error log ``` 2021-12-16T16:49:04,065+0800 [pulsar-io-18-23] WARN org.apache.pulsar.broker.web.PulsarWebResource - Policies not found for sample/ns1 namespace 2021-12-16T16:49:04,065+0800 [pulsar-io-18-23] WARN org.apache.pulsar.broker.service.ServerCnx - Failed to get Partitioned Metadata [/127.0.0.1:56739] persistent://sample/ns1/__change_events: Policies not found for sample/ns1 namespace org.apache.pulsar.broker.web.RestException: Policies not found for sample/ns1 namespace at org.apache.pulsar.broker.web.PulsarWebResource.lambda$checkLocalOrGetPeerReplicationCluster$12(PulsarWebResource.java:774) ~[classes/:?] at java.util.concurrent.CompletableFuture.uniAcceptNow(CompletableFuture.java:753) ~[?:?] at java.util.concurrent.CompletableFuture.uniAcceptStage(CompletableFuture.java:731) ~[?:?] at java.util.concurrent.CompletableFuture.thenAccept(CompletableFuture.java:2108) ~[?:?] at org.apache.pulsar.broker.web.PulsarWebResource.checkLocalOrGetPeerReplicationCluster(PulsarWebResource.java:745) ~[classes/:?] ``` I debugged the code. In fact, an try to delete the system topic when deleting the namespace. https://github.com/apache/pulsar/blob/ae2f1050cc65d19aa5367c45f71aaa43efc5af16/pulsar-broker/src/main/java/org/apache/pulsar/broker/admin/impl/NamespacesBase.java#L270 But Internal consumers and producers will reconnect, resulting in the auto create of the topic. Should we shut down these internal consumers(and producers) first? Ensure that the system topic is deleted correctly before deleting the bundle? Or directly redirect `deletenamespacebundleforcefully` method https://github.com/apache/pulsar/issues/10263#issuecomment-992098097 For your reference, If there is a problem, we can continue to discuss it, thanks. -- This is an automated message from the Apache Git Service.
