digi691 opened a new issue #5417: Broker hangs and crashes when listing non-persistent topics
URL: https://github.com/apache/pulsar/issues/5417
 
 
   **Describe the bug**
   On a Pulsar cluster w/ versions 2.3.0 or 2.4.1 when I send the API request /admin/v2/non-persistent/{tenant}/{namespace} to one of my brokers, the request just hangs.  If I send this request to frequently, the broker's API becomes unresponsive until the broker is restarted.  The broker also never logs the GET request.
   
   **To Reproduce**
   Steps to reproduce the behavior:
   1. Run step 2 on a pulsar broker that is in a cluster
   2. curl -v http://{HOST}:8080/admin/v2/non-persistent/{tenant}/{namespace}
   
   **Expected behavior**
   I expect pulsar to return an empty list.
   
   **Additional context**
   I could not reproduce on a standalone instance but the behavior is present on two of our clusters.  We do not use non-persistent topics but when trying to use Presto against Pulsar, the Presto jar tries to arbitrarily list non-persistent topics.
