Mickael Maison resolved KAFKA-1918. ----------------------------------- Resolution: Won't Do We are now removing ZooKeeper support so closing this issue. > System test for ZooKeeper quorum failure scenarios > -------------------------------------------------- > > Key: KAFKA-1918 > URL: https://issues.apache.org/jira/browse/KAFKA-1918 > Project: Kafka > Issue Type: Test > Components: system tests > Reporter: Omid Aladini > Priority: Major > > Following up on the [conversation on the mailing > list|http://mail-archives.apache.org/mod_mbox/kafka-users/201502.mbox/%3CCAHwHRrX3SAWDUGF5LjU4rrMUsqv%3DtJcyjX7OENeL5C_V5o3tCw%40mail.gmail.com%3E], > the FAQ writes: > {quote} > Once the Zookeeper quorum is down, brokers could result in a bad state and > could not normally serve client requests, etc. Although when Zookeeper quorum > recovers, the Kafka brokers should be able to resume to normal state > automatically, _there are still a few +corner cases+ the they cannot and a > hard kill-and-recovery is required to bring it back to normal_. Hence it is > recommended to closely monitor your zookeeper cluster and provision it so > that it is performant. > {quote} > As ZK quorum failures are inevitable (due to rolling upgrades of ZK, leader > hardware failure, etc), it would be great to identify the corner cases (if > they still exist) and fix them if necessary. -- This message was sent by Atlassian Jira (v8.20.10#820010)
