Comma
Why is the comma needed in "I entered the hallway, and knocked on the door." I have seen this use often in books and think it is incorrect.

You're right, no comma is needed. This is a sentence with a compound predicate and a single subject. If there were a second subject, then it be would a compound sentence, and a comma would be required.
I entered the hallway and knocked on the door.
