logstash 使用webhdfs 上传文件出现的问题

记录一次 logstash 6.5.4使用webhdfs插件向hdfs导入数据错误：

[WARN ][logstash.outputs.webhdfs ] Failed to flush outgoing items {:outgoing_count=>1, :exception=>"LogStash::Error", 
:backtrace=>[

经过分析：
是webhdfs使用不当的原因在官网里的推荐配置是这样

而我没有完全按照该格式

解决方法：

1. path最终我替换成了/user/ogstash/logs/output.txt
2. 加上dt=
