> Currently, different partitions can be picked up for the same input split
> based on the
> serdes' etc. And, we dont allow to change the schema for
> LazyColumnarBinarySerDe.
> Instead of that, different partitions should be part of the same split, only
> if the
> partition schemas exactly match. The operator tree object inspectors should
> be based
> on the partition schema. That would give greater flexibility and also help
> using binary serde with rcfile
