zbentley opened a new issue #13172:
URL: https://github.com/apache/pulsar/issues/13172
**Describe the bug**
Using a standalone broker built at HEAD (as of 12/7/2021), attempting to
delete topics a second or two after they are created returns a 500 error and a
stacktrace.
This occurs primarily in tenant/namespace combos that are also created very
shortly before the topic deletion is attempted (e.g. I see this in test code a
lot).
This error is intermittent; it does not occur every time, and sometimes
topic deletion is successful.
**To Reproduce**
1. Ensure a standalone broker is running.
2. Create a tenant, namespace, and persistent topic in that namespace. Do
these creation operations back to back, milliseconds or less apart.
3. Attempt to delete that topic via the management API.
4. Do steps 2-3 repeatedly; the error should eventually occur.
**Expected behavior**
Topic deletion should always succeed.
**Desktop (please complete the following information):**
- OS: MacOS 11.6.1, pulsar client 2.8.1.
**Client stacktrace:**
```
