filebeat+kafka失败

filebeat端配置

#----------------------------- Kafka output --------------------------------
output.kafka:
  # initial brokers for reading cluster metadata
  hosts: ["10.88.128.88:9092"]
  version: "0.8.2"

  topic: 'abc'
  #partition.round_robin:
  #  reachable_only: false

  required_acks: 1
  compression: none 
  #max_message_bytes: 1000000

报错如下：

上网查，filebeat解析的时候要解析到主机名，

所以绑定hosts如下

　　10.88.128.88 test43

问题搞定

按照报错，filebeat应该是先以配置的IP获取hostname，然后按照hostname连接kafka，如果通过hostname找不到对方服务器，则报错，所以需要在filebeat机器上绑定对方机器的hosts，暂不理解filebeat为什么要这么做。

如果目标机器中hosts文件书写有误，也会报错（filebeat向kafka中传递数据的时候还会检查目标机器的hosts文件）

开始还以为kafka版本太新，修改为filebeat目前支持的稳定版0.8.2都出问题，反复查，绑定hosts问题搞定。
