Subject [jira] [Updated] (HIVE-6938) Add Support for Parquet Column Rename
Date Tue, 13 May 2014 21:53:16 GMT


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
> Parquet should allow for either columnar (index based) access or name based access because
it can support either.
