Daniel Weeks updated HIVE-6938:
-------------------------------

    Attachment: HIVE-6938.3.patch

Updated to use global switch until HIVE-6936 is resolved.  This means all tables will be treated
the same until input formats have access to table properties.

> Parquet was originally introduced without 'replace columns' support in ql.  In addition,
the default behavior for parquet is to access columns by name as opposed to by index by the
Serde.  
> Parquet should allow for either columnar (index based) access or name based access because
it can support either.
