 In particular, I was curious if it teaches the .20 API?  The first edition explicitly taught
.19 because .20 wasn't quite vetted at the time he wrote it.  He even explains that in the
book.

I have access to a safaribooksonline account and according to a quick 
scan:

What’s New in the Second Edition?
The second edition has two new chapters on Hive and Sqoop (Chapters 12 
and 15), a
new section covering Avro (in Chapter 4), an introduction to the new 
security features
in Hadoop (in Chapter 9), and a new case study on analyzing massive 
network graphs
using Hadoop (in Chapter 16).
This edition continues to describe the 0.20 release series of Apache 
Hadoop, since this
was the latest stable release at the time of writing. New features from 
later releases are
occasionally mentioned in the text, however, with reference to the 
version that they
were introduced in.

you could also check out amazon's "look inside" functionality to check 
a few key pages once you find the second edition.

hope this is of some help.
