> As part of HIVE-6405's attempt to make HCatalog and Hive behave in similar
> ways with regards to immutable tables, this is a companion task to introduce
> the notion of an immutable table, wherein all tables are not immutable by
> default, and have this be a table property. If this property is set for a
> table, and we attempt to write to a table that already has data (or a
> partition), disallow "INSERT INTO" into it from hive(if destination directory
> is non-empty). This property being set will allow hive to mimic HCatalog's
> current immutable-table property.
