使用kafkacat查找kafka集群的lead

Question

我在使用 tutorial 创建的 docker 个容器中有 kafka 集群。当我运行 kafkacat -L -b kafka-1:19092 我得到：

Metadata for all topics (from broker 1: kafka-1:19092/1):
 3 brokers:
  broker 2 at kafka-2:29092
  broker 3 at kafka-3:39092
  broker 1 at kafka-1:19092
 1 topics:
  topic "__confluent.support.metrics" with 1 partitions:
    partition 0, leader 2, replicas: 2,3, isrs: 2,3

如何找到牵头经纪人？我想杀死它并在选举新领导后查看集群的行为。

Answer 1

集群有一个 控制器。

话题有领导

topic "__confluent.support.metrics" with 1 partitions:
    partition 0, <b>leader 2</b>, replicas: 2,3, isrs: 2,3
