Presto 无法使用本地文件连接器创建注入器

Question

我在 macOS 10.11 上使用 presto-server-0.149。仅出于测试目的，我运行一个节点，一切正常。当我添加 etc/catalog/localfile.properties 时：

connector.name=localfile
presto-logs.http-request-log-location=/var/log/apache2/access_log

我收到以下错误：

更新

根据下面 Dain Sundstrom 的回答，我解决了我的问题。结果发现 Local File Connector 的 fb 文档不正确。由于我需要获取一些东西来提供给 Presto 以测试本地文件连接器，因此我将配置文件路径更改为 Presto 自己的请求日志：

presto-logs.http-request-log.location=/var/presto/data/var/log/http-request.log

Answer 1

您的配置有误属性。应该是：

presto-logs.http-request-log.location=/var/log/apache2/access_log

此外，此连接器只能处理 Presto 本身创建的 http 日志格式，因此您需要重新配置 Apache2 服务器以输出相同的格式。
