      Description

      In 1,1, if an endpoint is available on the broker processing a metadata request, but the corresponding listener is not available on the leader of a partition, LEADER_NOT_AVAILABLE is returned (earlier versions returned UNKNOWN_SERVER_ERROR). This could indicate broker misconfiguration where some brokers are not configured with all listeners or it could indicate a transient error when listeners are dynamically added, We want to treat the error as a transient error to process dynamic updates, but we should notify clients of the actual error. This change should be made when MetadataRequest version is updated so that LEADER_NOT_AVAILABLE is returned to older clients.

      SeeĀ https://cwiki.apache.org/confluence/display/KAFKA/KIP-226+-+Dynamic+Broker+Configuration andĀ  https://github.com/apache/kafka/pull/4539 for details.
