Jason Gustafson created KAFKA-6394: -------------------------------------- Summary: Prevent misconfiguration of advertised listeners Key: KAFKA-6394 URL: https://issues.apache.org/jira/browse/KAFKA-6394 Project: Kafka Issue Type: Bug Reporter: Jason Gustafson
We don't really have any protection from misconfiguration of the advertised listeners. Sometimes users will copy the config from one host to another during an upgrade. They may remember to update the broker id, but forget about the advertised listeners. It can be surprisingly difficult to detect this unless you know to look for it (e.g. you might just see a lot of NotLeaderForPartition errors as the fetchers connect to the wrong broker). It may not be totally foolproof, but it's probably enough for the common misconfiguration case to check existing brokers to see whether there are any which have already registered the advertised listener. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
