> *ColumnStatsMerger classes contain a lot of duplicate code which is not 
> specific to the data type, and that could therefore be lifted to a common 
> parent class.
> This phenomenon is bound to become even worse if we keep enriching further 
> our supported set of statistics as we did in the context of HIVE-26221.
> The current ticket aims at improving the modularity and code reuse of the 
> *ColumnStatsMerger classes, while improving unit-test coverage to cover all 
> classes and support more use-cases.
