apache-drill - 在 Windows 10 上以嵌入式模式启动 Apache Drill 时出错

Question

我正在尝试在 Windows 10 x64(使用 Oracle JVM 1.8.0_131)上以嵌入式模式启动 Apache Drill 1.10。启动命令时

sqlline.bat -u "jdbc:drill:zk=local"

我得到以下信息:

Error during udf area creation [/C:/Users/<user>/drill/udf/registry] on file system [file:///] (state=,code=0)

因此，经过一些谷歌搜索后，我以这种方式更改了drill-override.conf 文件:

drill.exec: {
  cluster-id: "drillbits1",
  zk.connect: "localhost:2181",
  udf: {
    # number of retry attempts to update remote function registry
    # if registry version was changed during update
    retry-attempts: 10,
    directory: {
      # Override this property if custom file system should be used to create remote directories
      # instead of default taken from Hadoop configuration
      fs: "file:///",
      # Set this property if custom absolute root should be used for remote directories
      root: "/c:/work"
    }
  }
}

然后我检查了以下内容:

为文件夹设置了适当的权限

控制台以管理员身份启动

但我仍然得到同样的错误:

Error during udf area creation [/c:/work/drill/udf/registry] on file system [file:///] (state=,code=0)

我无法禁用 UDF，因为我没有事件连接。

有什么建议？

似乎与文件夹的所有权有关，根据 this关联。
来自链接的解决方案的详细信息引用如下

Run these commands before the first time you are running sqlline.bat.

mkdir %userprofile%\drill

mkdir %userprofile%\drill\udf

mkdir %userprofile%\drill\udf\registry

mkdir %userprofile%\drill\udf\tmp

mkdir %userprofile%\drill\udf\staging

takeown /R /F %userprofile%\drill
