> High priority issues with schema evolution for the ORC file format.
> Schema evolution here is limited to adding new columns and a few cases of column type-widening (e.g. int to bigint).
> Renaming columns, deleting column, moving columns and other schema evolution were not pursued due to lack of importance and lack of time.  Also, it appears a much more sophisticated metadata would be needed to support them.
> The biggest issues for users have been adding new columns for ACID table (HIVE-11421 Support Schema evolution for ACID tables) and vectorization (HIVE-10598 Vectorization borks when column is added to table).
