1、Broker health check failed with TopicVersion.V2 but it's ok with TopicVersion.V1, The failed reason is:

2021-12-27T13:21:17,350+0800 [pulsar-io-4-71] WARN  org.apache.pulsar.client.impl.BinaryProtoLookupService - [persistent://pulsar/hidden-ip:8080/healthcheck] failed to get Partitioned metadata : {"errorMsg":"Policies not found for pulsar/hidden-ip:8080 namespace","reqId":1293596554348340272, "remote":"", "local":""}

Policies not found for namespace pulsar/host:8080 under znode admin/policies.

But Why v1 is successful? v1's healthcheck topic name is global, checkReplication is skipped.

I cannot decide the best solution to fix it.
