Julien Le Dem commented on HIVE-6938:
-------------------------------------

I find the terminology "columnar.access" confusing but otherwise, this looks good to me.

> 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.
