Question

我在macOS 10.11上使用presto-server-0.149。仅仅为了测试目的，我运行一个节点，一切都很好。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Dain Sundstrom在下面的回答，我能够解决我的问题。原来，Local File Connector的fb文档不正确。由于我需要为Presto提供一些东西来测试localfile连接器，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

配置属性中有拼写错误。它应该是：

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

此外，此连接器只能处理Presto自身创建的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。

Presto无法使用localfile连接器创建注入器
