    [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.
