Onur Karaman created KAFKA-5083: ----------------------------------- Summary: always leave the last surviving member of the ISR in ZK Key: KAFKA-5083 URL: https://issues.apache.org/jira/browse/KAFKA-5083 Project: Kafka Issue Type: Sub-task Reporter: Onur Karaman Assignee: Onur Karaman
Currently we erase ISR membership if the replica to be removed from the ISR is the last surviving member of the ISR and unclean leader election is enabled for the corresponding topic. We should investigate leaving the last replica in ISR in ZK, independent of whether unclean leader election is enabled or not. That way, if people re-disabled unclean leader election, we can still try to elect the leader from the last in-sync replica. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
