A lot will depend on how the pup is raised in your absence. He will remember you, but probably not as his owner. You will need to re-establish the relationship once you are with him.
If you are staying in the same place that the pup will be, your scent will be all over the place and he will remember and associate it with 'home'. If he will be in a different place, leave a piece or two of old, recently worn (not washed) clothing for his care-takers to leave where he can smell it/them.
I am not certain why you think he would attack you simply because he hasn't seen you for a while. If you have this fear, then I wonder if you know and trust the breed or the people who are/will be caring for your dog. Are you also afraid he will attack strangers?
Rotties are good animals and if raised properly will not attack for no reason. Like any dog, they have to be raised and educated in what is expected of them. They need human interaction, obedience training, and proper stimulation through play and exercise as well as food, water, and places to sleep and potty. He should already be getting these needs filled. He cannot be left to his own devices and be expected to be a well-behaved animal.
I do question the timing of getting the puppy at this time. Is there some reason you didn't wait until you returned to get him?
