Hi ,

  I have my source code written in 0.19.1 Hadoop API and want to shift  
it to newer API 0.20.20. Any clue on good documentation on migrating  
from older version to newer version will be very helpful.

Thanks.
Prashant

In the *Chuck Lam's* book *Hadoop in Action  the* upgrade from 0.19.1 to
0.20.0 is mentioned. Also there are many pieces of information on web,
but they are scattered around.

Hadoop : the definitive guide also talks about migration

Thanks Shi and Madhu, I have look through the points in both the books.
The description is limited though. One has to dig the framework code to
actually realize the precise alternatives. I for once was thinking of
writing a help guide for somebody. But then I am not good with that,
Hope you all can help me improve it.

Thanks again.
