FileBeat: error loading config file: yaml: did not find expected key

在运行./filebeat时报出error错误：

Exiting: error loading config file: yaml: line 197: did not find expected key

发现是格式错误，空格多了，去除点多余的空格

#============================== Kafka Output ===============================
output.kafka:
  # initial brokers for reading cluster metadata
     hosts: ["hadoop102:9092"]
  #
  #     # message topic selection + partitioning
     topic: 'test'
     partition.round_robin:
     reachable_only: false

     required_acks: 1
     compression: gzip
     max_message_bytes: 1000000

之后运行正常，可以准确输出到kafka。
