### Motivation **Background**: The Pulsar client will close the socket if it receives a ServiceNotReady error when doing a lookup. see https://github.com/apache/pulsar/blob/af20a8a8623055bab665e566b3f54f6f884d121d/pulsar-client/src/main/java/org/apache/pulsar/client/impl/ClientCnx.java#L1193-L1200 Closing the socket causes the other consumer or producer to reconnect and does not make the lookup more efficient. There are two cases that should be improved: - If the topic is unloading, the broker responds with a `ServiceNotReady` error. - If the broker gets a metadata read/write error, the broker responds with a `ServiceNotReady` error. ### Modifications - Respond to the client with a `MetadataError` if the broker gets a metadata read/write error. - Respond to the client with a `MetadataError` if the topic is unloading ### Documentation <!-- DO NOT REMOVE THIS SECTION.
