我试图在Windows 7上运行Apache Drill，我有文档中提供的要求但是当我在终端中运行它时出现此错误：

当我去tmp文件夹时，我只找到一个文件

有谁知道如何解决这个问题？谢谢

Answer 1

删除/移动文件夹/tmp/drill/sys.storage_plugins＆amp;重启演习。它会在启动钻取时创建文件夹。现在通过比较旧的＆amp; amp;新。它对我有用。

Answer 2

谢谢你们，当我用其他计算机在同一位置创建的文件替换/tmp/drill/sys.storage_plugins时，它仍然有用，我仍然不知道为什么这个不能创建所有这些文件，但至少现在它可以工作了！

Answer 3

这是2018年03 02，这个错误仍然出现在人们（像我一样）试图安装＆amp;在Windows 10上以嵌入式模式运行Apache Drill ...

这里为我工作的东西：安装只钻到

C：\阿帕奇钻-1.12.0 *

请注意，这会创建一个

C：\ tmp \ sys.storage_plugins \目录比删除这个目录更重要，我只是将这个目录暂时移到我的笔记本电脑的桌面上;

然后我重新启动了Drill Shell，如下所示......

启动一个常见的Windows 10 cmd控制台

cd到C：\ apache-drill-1.12.0 \ bin \ EXECUTE这个命令： sqlline sqlline.bat -u“jdbc：drill：zk = local; schema = dfs”

结果：我得到以下（WONDERFUL）初始化输出：

DRILL_ARGS - “sqlline.bat -u jdbc：drill：zk = local; schema = dfs”计算HADOOP_CLASSPATH ...未检测到HBASE_HOME ...计算钻取类路径...拾取_JAVA_OPTIONS：-Xmx512M -Xms512M Mar 02,20188 8:36:33 PM org.glassfish.jersey.server.ApplicationHandler initialize INFO：Initiating Jersey application，version Jersey：2.8 2014-04-29 01:25:26 ...属性“url”是需要apache drill 1.12.0“人们可以设想并相信什么，钻可以查询”

0：jdbc：drill：zk = local＆gt;

从这里我发布了“SHOW DATABASES”;命令......它工作了！
