poorbarcode opened a new pull request, #21947: URL: https://github.com/apache/pulsar/pull/21947
### Motivation **Steps to reproduce the issue** - Enable replication. - Send `10` messages to the local cluster then close the producer. - Call `pulsar-admin topics unload <topic>` and get an error due to the internal producer of the replicator close failing. - The topic closed failed, so we assumed the topic could work as expected, but the replication stopped. **Root cause** - `pulsar-admin topics unload <topic>` will wait for the clients(including `consumers & producers & replicators`) to close successfully, and it will fail if clients can not be closed successfully. - `replicator.producer` close failed causing the Admin API to fail, but there is a scheduled task that will retry to close `replicator.producer` which causes replication to stop. see https://github.com/apache/pulsar/blob/master/pulsar-broker/src/main/java/org/apache/pulsar/broker/service/AbstractReplicator.java#L209 ### Modifications since the "replicator.producer.closeAsync()" will retry after it fails, the topic unload should be successful. ### Documentation <!-- DO NOT REMOVE THIS SECTION.
