user11541: Gautama Buddha died and had attained final Nirvana. His cleaving to existing objects had ceased. His ignorance was destroyed. He had no upadana or karma left. Yet Buddha said that he will take rebirth as Metteyya. 

And the Blessed One replied: "I am not the first Buddha who came upon
  earth, nor shall I be the last. In due time another Buddha will arise
  in the world, a Holy One, a supremely enlightened One, endowed with
  wisdom in conduct, auspicious, knowing the universe, an incomparable
  leader of men, a master of angels and mortals. He will reveal to you
  the same eternal truths which I have taught you. He will preach his
  religion, glorious in its origin, glorious at the climax, and glorious
  at the goal, in the spirit and in the letter. He will proclaim a
  religious life, wholly perfect and pure; such as I now proclaim."
Ananda said: "How shall we know him?" The Blessed One said: "He will
  be known as Metteyya, which means 'he whose name is kindness.'"

In above quote it is clear that Buddha says another Buddha will rise. Is it not the rebirth of Buddha ? (I am not saying rebirth of Gautama but Buddha)
My question is if Nirvana means cessation of birth then how is it possible for Buddha to take rebirth?  

user111: He never said that! Buddha Metteya is a different person. There have been many Buddhas in the past and all of them are different persons.
Buddha is a title. Think of it as king of a country. How many kings there have been? Are they all one person?
This is another good example for how easily people misinterpret the suttas. Just because one is able to read the Suttas(either Pali or English) one may not be able to grasp the true meaning without a proper teacher.
