David Jacot reassigned KAFKA-7335: ---------------------------------- Assignee: David Jacot > Store clusterId locally to ensure broker joins the right cluster > ---------------------------------------------------------------- > > Key: KAFKA-7335 > URL: https://issues.apache.org/jira/browse/KAFKA-7335 > Project: Kafka > Issue Type: Improvement > Reporter: Jason Gustafson > Assignee: David Jacot > Priority: Major > > We have seen situations where a broker somehow got the wrong configuration > and joined a different cluster than the one it was previously registered in. > This can create various kinds of metadata inconsistencies in the cluster and > can be difficult to debug. It was suggested in > [KIP-78|https://cwiki.apache.org/confluence/display/KAFKA/KIP-78%3A+Cluster+Id] > that we could store the clusterId locally after initial registration and > verify upon startup that the locally stored value matches what is in > zookeeper. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
