Lefty Leverenz commented on HIVE-6938:
--------------------------------------
I mentioned this in the Limitations section of the Parquet wikidoc, but it
could use an example and some usage notes in a new subsection.

> 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.
