iosdev747 opened a new issue, #23092: URL: https://github.com/apache/pulsar/issues/23092
### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Read release policy - [X] I understand that unsupported versions don't get bug fixes. I will attempt to reproduce the issue on a supported version of Pulsar client and Pulsar broker. ### Version Pulsar: 3.0.5 Admin Client: 3.0.5 ### Minimal reproduce step - 2 clusters (cluster-1, cluster-2) - Tenant present in all clusters. (tenant1) - Namespace (tenant1/ns1) present in only one cluster (cluster-1) - When updating the ns-isolation-policy for cluster-2 with policy data as `tenant1/.*`, `setNamespaceIsolationPolicy()` fails. This serves usecases where other namespaces under this tenant should be a part of certain broker group. This used to work in 2.9.x and 2.10.x. ### What did you expect to see? 200 returned and setNamespaceIsolationPolicy() setting up the ns-isolation-policy correctly. This should not try to unload namespaces which are not present in current cluster. ### What did you see instead? PR that introduced this change: https://github.com/apache/pulsar/pull/15527 [Here](https://github.com/apache/pulsar/blob/fdeeba597d1689f858a0eec072441872ad33c0ed/pulsar-broker/src/main/java/org/apache/pulsar/broker/admin/impl/ClustersBase.java#L737), set policy call tries to unload all matching namespaces (all bundles). There should be a check that namespace should be present in the current cluster. ### Anything else? Apart from the above issue, this way of unloading all the namespace bundles is very impactful (That will definitely lead to some amount of downtime). If some namespaces are already present in the correct broker group (as per ns isolation policy), then those namespace bundles should not be unloaded. For a broker group with many small namespaces, this will lead to timeouts and or even 5xx (when there are too many bundles unloaded). One of such scenario: ``` java.util.concurrent.CompletionException: org.apache.pulsar.client.admin.PulsarAdminException$ServerSideErrorException: --- An unexpected error occurred in the server ---
