> Support configurable null format for tables and writing out to directory.
> Using a non-default null format is a bit while creating a table, and pretty much impossible to export the data to local filesystem using insert overwrite directory.
> The patch enhances the SQL syntax to support 'NULL DEFINED AS' construct for create table as well as insert overwrite directory.
