Fwd: Mapreduce for beginner
Hi,
I start learning about mapreduce with Hadoop by wordcount example. I am a
bit confused about the frontier between the map and reduce program. Is
there a standard format for the map output and the reduce input? Is there
a full explanation of java classes used somewhere? I also appreciate to
learning in other languages (phyton, C++ ...). Any suggestion is welcome.
Thanks.
Regards
Olivier

Given that your questions are very broad and at high level, I would suggest
that you should pick up a book or such to go through that. The Hadoop:
Definitive Guide by Tom White is a great book to start with it.
