> During the creation of external tables with a specified location, the general
> expectation is that the data is already present or the data might be
> externally added to the location without involving HMS. So, it is really not
> required to have read and write permissions on an external table during the
> creation time.
> This enhancement can address security concerns where currently the users had
> to be granted unnecessary write permissions on an external file location when
> the table is only used for reading the data.
> Update/delete operations would anyway require write permissions.
> CTAS query with location specified is expected to fail at runtime (trying to
> create staging directory under table location) without WRITE permissions.
