Delivery Status Notification (Failure)
Dear all,
I am a new Hadoop user and am confused a little bit about the difference
between Hadoop and MapReduce. Could anyone please clear me?
Thanks!
Simon

Simon,
Hadoop is an implementation of the Google's MapReduce framework. So it
does everything that is described in (say) the MapReduce paper.
I hope you confusion is resolved now.

Hi Edson,
Thank you for the answer. That's right MapReduce is the Google framework
based on two functions Map and Reduce. If I understood it correctly, Hadoop
is an implementation of Map and Reduce functions in MapReduce. My question
is: Does Hadoop includes MapReduce framework of Google as well?
Regards
Simon

Hi Simon,
MapReduce is a framework developed by Google that uses a
programming model based in two functions called Map and Reduce,
Both the framework and the programming model are called MapReduce, right?
Hadoop is an open-source implementation of MapReduce.
HTH,

Thanks Abhishek for your answer. But sorry still I don't understand... What
do you mean by the "the runtime/programming support needed for MapReduce"?
Could you please mention some other implementations of MapReduce?
Cheers
Simon

Hadoop is an open source implementation of the runtime/programming
support needed for MapReduce.
Several different implementations of MapReduce are possible. Google
has its own that is different from Hadoop.

You can find more about MapReduce here:
http://labs.google.com/papers/mapreduce.html
Some of the implementations (like Hadoop) are listed on this page:
