问题
我正在使用 Apache Drill 来打开一个 Parquet 文件。
在运行 drill-embedded 之后，根据 官方文档，我运行以下命令：
apache drill> SELECT * FROM `dfs`.`/path/to/my/file.parquet`;
但我收到以下错误信息：
错误: INTERNAL_ERROR ERROR: 无法读取字段 "timeProcess"，因为 "this.parquetReaderStats" 为空
片段: 0:0
请查看日志以获取更多信息。

错误是次要的，它不会显示底层问题。如果您来到Drill Slack频道或用户邮件列表，就可以进一步调查。带上的重要信息包括Drill的版本和失败查询的JSON配置文件（可从Drill Web界面的"Profiles"选项卡中获得，网址为http://localhost:8047，因为您正在运行嵌入式Drill）。
英文:
That error is a secondary one that doesn't reveal the underlying problem. If you come to the Drill Slack channel or user mailing list it will be possible to investigate fuether. Important information to bring you with is the version of Drill and the JSON profile of a failed query (accessible from the Profiles tab of the Drill web UI which will be at http://localhost:8047 since you're running embedded Drill).
