-Re: Good learning resources for 0.23?

Happy to help.
When you mean .23 API, do you mean how to write your own applications on top of YARN?
If so, you can start with hadoop-2 release docs:
There is also an example application (DistributedShell) you can look at for a simpler usage of YARN apis:
As you are probably aware, MapReduce applications itself don't need to change when you move to using hadoop-2.

I have found several websites and articles that discuss the philosophical differences between .20 and .23 but I'm looking for teaching/learning resources for getting into the guts and actually programming the thing. I'm pretty competent at .20 so I'm not looking for starter-level hadoop stuff. Rather, I'm looking for transitional resources to learn the specifics of the new design.
