kafka-cluster

问题 This question already has answers here : Connect to Kafka running in Docker (3 answers) Closed 4 months ago . I setup a kafka cluster using bitnami kafka and zookeeper and I wanted to view this cluster or at least one broker using kafdrop. I used docker compose to build all the components. I initially followed this tutorial and then added the kafdrop config in the docker-compose.yml version: '2' networks: kafka-net: driver: bridge services: zookeeper-server: image: 'bitnami/zookeeper:latest'

问题 We are trying to implement Kafka HA using kafka cluster. While doing R&D, we found that minimum number of nodes recommended for zookeeper & kafka brokers are 3. We understand that why zookeeper should have minimum 3 nodes, because for leader election minimum (n+1)/2 nodes should be up & running. But its not clear, why minimum 3 kafka brokers are required. Why can't we implement HA with 2 kafka brokers & 3 zookeepr nodes? 回答1: The minimum number of nodes of Zookeeper is 3 because of the quorum
