我目前正在学习使用大数据， 客户端：Windows 10 服务器端：CentOS7 elasticsearch，logstash和kibana已安装在服务器端， 作为客户端，我可以通过http://10.64.2.246:5601/访问kibana，一切都很酷。现在，我想学习如何将数据从我的PC传输到服务器端的elasticsearch。我已经在客户端下载了logstash。

我已经用2列从kaggle准备了数据。 我已经制作了我的conf文件

conf文件

input   {
    file    {
        path => "C:\Users\Charles\Desktop\DATA"
        start_position => "beginning"
        sincedb_path=>"/dev/null"
    }
}
filter  {
    csv     {
        separator=>","
        columns=>["Date","Price"]
    }
    mutate {convert =>["Price","float"]}
}
output{
    elasticsearch{
        host => "10.64.2.246"
        index=>"oil"
        document_type=>"minyaks"
    }
    stdout{}
}

这是我执行在客户端执行的conf文件的代码。

bin/logstash -f /Users/Charles/Desktop/DATA/logstash_oil.conf

这是显示的错误

需要某人向我解释。我遵循youtube上的指示，但是讲师是在本地进行的。

谢谢。
