poorbarcode opened a new pull request, #18194: URL: https://github.com/apache/pulsar/pull/18194
### Motivation If the namespace is deleted, the `cmd-lookup` will still keep retrying, because the error code sent to the client is `MetadataError`, and the client will retry when it gets `MetadataError`. No matter how many times it tries again, it will not succeed. https://github.com/apache/pulsar/blob/6cc30c93a05bb16b7ef62ffebc15ceb5e6efb502/pulsar-broker/src/main/java/org/apache/pulsar/broker/lookup/TopicLookupBase.java#L250-L257 ### Modifications If the namespace is deleted - the `cmd-lookup` will get the error code `TopicNotFound ` - the rest request will get the response code `404` - improve response message for `API topics` and `API namespaces` - `TODO` I will write a test later ### Documentation <!-- DO NOT REMOVE THIS SECTION.
