https://github.com/apache/carbondata/pull/1993 [CARBONDATA-2199] Fixed Dimension column after restructure getting wrong block datatype
Problem: Changing datatype of measure having sort_columns calls for restructure and after having restructure it changes the datatype to actual datatype for which accessing the data with changed datatype gives exception of incorrect length.
Solution: Store the datatype in DimensionInfo while restructuring and access the same datatype to get the block data type.
