Subject [jira] [Commented] (HIVE-6938) Add Support for Parquet Column Rename
Date Tue, 17 Jun 2014 02:35:02 GMT

Szehon Ho commented on HIVE-6938:
---------------------------------

Actually I took a quick look and it is straight-forward, test-output just needed to be regen'ed
after HIVE-7087 which removes lineage-info in golden files, the rest is the same.  Fix is
at HIVE-7245

> 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.
