我们有3个代理的Kafka集群，其中多个主题的复制因子为3。
发生了一个或多个Kafka经纪人自动关闭的情况。
server.log文件包含受控关闭消息：
[2020-02-04 17:25:36,156] INFO [KafkaServer id=10] Controlled shutdown succeeded (kafka.server.KafkaServer)
但是，controller.log在TRACE下方生成，指向Leader失衡率
[2020-02-04 17:25:23,350] TRACE [Controller id=10] Leader imbalance ratio for broker 9 is 1.0** (kafka.controller.KafkaController)

此问题的原因是什么，该问题会触发kafka经纪人自动关闭，并且kafka不在内部对其进行处理。
