Emm,I running in standalone mode, I tested the latest code and still have some problems. 1. Deleting a namespace may be 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.
