Manikumar updated KAFKA-12866: ------------------------------ Fix Version/s: 3.0.0 > Kafka requires ZK root access even when using a chroot > ------------------------------------------------------ > > Key: KAFKA-12866 > URL: https://issues.apache.org/jira/browse/KAFKA-12866 > Project: Kafka > Issue Type: Bug > Components: core, zkclient > Affects Versions: 2.6.1, 2.8.0, 2.7.1, 2.6.2 > Reporter: Igor Soarez > Assignee: Igor Soarez > Priority: Major > Fix For: 3.0.0 > > > When a Zookeeper chroot is configured, users do not expect Kafka to need > Zookeeper access outside of that chroot. > h1. Why is this important? > A zookeeper cluster may be shared with other Kafka clusters or even other > applications. It is an expected security practice to restrict each > cluster/application's access to it's own Zookeeper chroot. > h1. Steps to reproduce > h2. Zookeeper setup > Using the zkCli, create a chroot for Kafka, make it available to Kafka but > lock the root znode. > > {code:java} > [zk: localhost:2181(CONNECTED) 1] create /somechroot > Created /some > [zk: localhost:2181(CONNECTED) 2] setAcl /somechroot world:anyone:cdrwa > [zk: localhost:2181(CONNECTED) 3] addauth digest test:12345 > [zk: localhost:2181(CONNECTED) 4] setAcl / > digest:test:Mx1uO9GLtm1qaVAQ20Vh9ODgACg=:cdrwa{code} > > h2.

Expected behavior > The expected behavior here is that Kafka will use the chroot without issues. > h2.
