The state of World of Warcraft when  Demon hunters appeared with Legion was such that demon hunter trainers didn't really exist. Abilities appear automatically when the appropriate level is reached or quest completed. Demon hunters automatically get the ability to switch between their two initial specializations,  Havoc and  Vengeance.
