Lefty Leverenz commented on HIVE-6938:
--------------------------------------

Does this need additional documentation?  (See previous comment.)  If not, we can remove the
TODOC14 label.

> 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.
