> I want ask a question, why the admin to execute doAs in the next, don't
use sql to execute, i found your code is `doAs(admin, createTableAs)`, why not
is `doAs(admin,sql(createTableAs))`. And i found the DeltaCatalogRanger also
use doAs(user,mySql),but the HudiCatalog use doAs(user,sql(mySql)). Which is
the right way???

> @pan3793 could you give some advice
doAs code is
```
protected def doAs[T](user: String, f: => T): T = {
UserGroupInformation.createRemoteUser(user).doAs[T](
new PrivilegedExceptionAction[T] {
override def run(): T = f
})
}
```
If we not use spark.sql to execute our sql, it's only a string format???
