Apache Drill 模拟

Question

我正在尝试在我们的 Drill (1.6.0) 系统上构建安全性。我设法让安全用户身份验证工作(如文档中所述的 JPam)，但模拟似乎不起作用。它似乎通过管理员用户执行和获取，而不管谁通过 ODBC 登录。

我的drill-override.conf文件配置如下:

  drill.exec: {
  cluster-id: "drillbits1",
  zk.connect: "localhost:2181",
  impersonation: {
    enabled: true,
    max_chained_user_hops: 3
  },
  security.user.auth {
      enabled: true,
      packages += "org.apache.drill.exec.rpc.user.security",
      impl: "pam",
      pam_profiles: [ "sudo", "login" ]  
  }
}

我们也只在一台服务器上使用 Drill，因此我正在运行 drill-embedded 来启动它。故障排除:

对此有什么想法吗？

我也考虑过做我自己的内置安全，但我无法从 SQL 查询中检索用户名。我尝试了以下但没有任何运气:

CURRENT_USER()  
USER()   
SESSION_USER()   

对这种方法有什么想法吗？

Answer 1

我建议创建一个不同的 pam 配置文件(比如 drill)而不是登录和 sudo。 然后在/etc/pam.d/目录下创建 drill 文件，内容为:

#%PAM-1.0
auth include password-auth
account include password-auth

要运行连接:

select * from sys.connections;
