Review comment:
   shall we do the same thing for CREATE NAMESPACE? We can do it in a 
separated PR.

Review comment:
   We don't need `SQLConfHelper`. We can get the conf by 
`session.sessionState.conf`

Review comment:
   and can you refer to the code for qualifying the path string in v1 
commands? Let's make sure v1 and v2 are truly consistent.

Review comment:
   it's a bit weird to have `URI` in the logical plan, can we keep it as 
`String` type and just put the qualified path string?
