--------------------------------------------------------------------

[~cenyuhai] i am working on some prs for hive, all of them are failing due to this issue specialy the carbondata vs orc performance pr i guess earlier short,int were taking as long but now they are taking their respective ranges in master branch, so i think its better to remove this issue earlier so i can easily continue ,can i create a seperate pr for correcting them?
