David Arthur created KAFKA-16463: ------------------------------------ Summary: Automatically delete metadata log directory on ZK brokers Key: KAFKA-16463 URL: https://issues.apache.org/jira/browse/KAFKA-16463 Project: Kafka Issue Type: Improvement Reporter: David Arthur Assignee: David Arthur Fix For: 3.8.0
Throughout the process of a ZK to KRaft migration, the operator has the choice to revert back to ZK mode. Once this is done, there will be a copy of the metadata log on each broker in the cluster. In order to re-attempt the migration in the future, this metadata log needs to be deleted. This can be pretty burdensome to the operator for large clusters. To improve this, we can automatically delete any metadata log present during startup of a ZK broker. This is safe to do because the ZK broker will just re-replicate the metadata log from the active controller. -- This message was sent by Atlassian Jira (v8.20.10#820010)
