Thejas M Nair commented on HIVE-13990:
--------------------------------------
At the very least, I think we should cache the information that ACL is not
supported after the UnsupportedException is thrown. Otherwise, it could end up
being very expensive to deal with that exception for every file check.
> Client should not check dfs.namenode.acls.enabled to determine if extended
> ACLs are supported

> dfs.namenode.acls.enabled is a server side configuration and the client
> should not presume to know how the server is configured. Barring a method for
> querying the NN whether ACLs are supported the client should try and catch
> the appropriate exception.
