Rajini Sivaram created KAFKA-6546: ------------------------------------- Summary: Add ENDPOINT_NOT_FOUND_ON_LEADER error code for missing listener Key: KAFKA-6546 URL: https://issues.apache.org/jira/browse/KAFKA-6546 Project: Kafka Issue Type: Improvement Components: core Reporter: Rajini Sivaram Assignee: Rajini Sivaram Fix For: 1.2.0
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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
