Hardwood flooring

I had carpet floors and ripped it off. its has plywood now and I plan to have eng. wood installed. I want to know if gluing it will create any problems as I think using nails , staples, is not recommended for the thickness of wood I am using ( 3/8 inch ).
So does gluing create problems like squeaking etc.
Also if its glued is it difficult to remove a certain area if its damaged in the future.
( the room is above my basement ).
