[GitHub] [pulsar] MarvinCai commented on issue #7397: Failed to create subscription on non-persistent topic.

   I can reproduce the issue by starting standalone and create tenant/namespace then try to create subscription on non-persistent topic with command:
   `./pulsar-admin topics create-subscription  -s subscription non-persistent://tenant/namespace/topic`
   and I see HTTP 500 Internal Server Error
   I think the reason is the create-subscription is intended for persistent topic and it'll try to cast the created topic to PersistentTopic: https://github.com/apache/pulsar/blame/master/pulsar-broker/src/main/java/org/apache/pulsar/broker/admin/impl/PersistentTopicsBase.java#L1843 so it'll fail if we provide a non persistent topic name.
   Do we want to add support for non-persistent topic here?
