giacomo-porro opened a new issue #9449: URL: https://github.com/apache/pulsar/issues/9449
**Describe the bug** Creating a consumer subscribed on different topics on different namespaces throws an error even if no regex pattern is used ( as per https://pulsar.incubator.apache.org/docs/en/concepts-messaging/#multi-topic-subscriptions ) **To Reproduce** Steps to reproduce the behavior: 1. Create a custom tenant on pulsar with pulsar admin ```bin/pulsar-admin tenants create my-tenant``` 2. Create 2 different namespaces on that tenant with pulsar admin ``` bin/pulsar-admin namespaces create my-tenant/ns1 bin/pulsar-admin namespaces create my-tenant/ns2 ``` 3. Create 2 topics, one per namespace with pulsar admin ``` bin/pulsar-admin topics create my-tenant/ns1/topic-1 bin/pulsar-admin topics create my-tenant/ns2/topic-2 ``` 4. Run this code ```python import pulsar from _pulsar import ConsumerType def handle(consumer, message): print(message.value()) client = pulsar.Client(service_url="pulsar://localhost:36650") consumer = client.subscribe( topic=["persistent://my-tenant/ns1/topic-1", "persistent://my-tenant/ns2/topic-2"], subscription_name="my-sub", consumer_type=ConsumerType.Shared, message_listener=handle, consumer_name="my-consumer-name" ) ``` I get the error ERROR [0x11a3f7dc0] MultiTopicsConsumerImpl:737 | Different namespace name. expected: qa/users now:qa/accounts I tried the same setup with the Java client and it works as expected **Expected behavior** The consumer should not throw an error and just connect correctly **Desktop (please complete the following information):** - OS: MacOSX Catalina **Additional context** I tried with pulsar python client 2.6.1, 2.6.2 and 2.7.0 and all of them had the same issue ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
