manishnalla1994 opened a new pull request #3348: [CARBONDATA-3486] Fix Serialization/Deserialization issue with DataType
URL:
https://github.com/apache/carbondata/pull/3348
Problem: When we use old store and do alter add sort columns on it then query on the old segment, serialization/de-serialization issue comes for Filter Column of Measure type which has been changed in Sort Column as it is being de-serialized by ObjectSerialization. This fails the check and the query.
Solution: Checked the datatype based on Datatype ID and not on the object.
