我试图在我们的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（JPam，如文档中所述），但模拟似乎不起作用。它似乎通过管理员用户执行和获取，无论谁通过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。故障排除：

有关于此的任何想法吗？
我还考虑过自己的内置安全性，但是我无法从SQL查询中检索用户名。我没有运气就试过以下内容：
CURRENT_USER()
USER()
SESSION_USER()
关于这种方法的任何想法？
