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.
