This post is part of the Debug 101 series. If you missed the previous post in this series, check it out here: Nodes successfully joined, not! We’re in the middle of deploying Apache Kafka to Kubernetes the cloud native-way - by totally removing the Zookeeper dependency and using etcd, instead. This means that service registry/discovery and other internal Kafka to Zookeeper operations will be dispatched to a pre-existing etcd cluster.

Debug 101 Today we’re starting a new series called Debug 101, which deals with those issues that gave us particularly bad headaches and took a large amount of time to debug, understand and fix. We believe strongly in open source software and open issue resolution, and we try to describe our problems and suggest fixes as we go, so you don’t have to shave that yak. We already have, and they yak looks awesome.
