    Description

      ConsumerCoordinator installs a Metadata.Listener in order to update pattern subscriptions after metadata changes. The listener is invoked from NetworkClient.poll, which could happen in the heartbeat thread. Currently, however, there is no synchronization in SubscriptionState to make this safe.
