> ORC schema evolution should not completely disable PPD

> Project: Hive
> Issue Type: Bug
> Affects Versions: 2.2.0
> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran
> Priority: Critical

>
> Follow up for HIVE-14214 which completely shuts off PPD when there is any
> schema evolution. Some evolutions are safer for PPD like
> byte -> short -> int -> long
> -float -> double- (This is unsafe, see comments in SchemaEvolution.java in
> the patch)
> varchar <-> string (string to char, varchar to char and vice versa is also
> unsafe conversion as Orc stores internal index with padded spaces for char)
> For all other conversions we can disable PPD for that specific column that
> has evolved by returning TruthValue.YES_NO
