Description: In our own Hadoop learning activities, we’re constantly struck by how little
beginner-level content is available. For almost any topic, we see two things:
high-level marketing blurbs with pretty pictures; and dense, low-level, narrowly
focused descriptions. What are missing are solid entry-level explanations
that add substance to the marketing fluff and help someone with little or no
background knowledge bridge the gap to the more advanced material. Every
chapter in this book was written with this goal in mind: to clearly explain the
chapter’s concept, explain why it’s significant in the Hadoop universe, and
show how you can get started with it.
No matter how much (or how little) you know about Hadoop, getting started
with the technology is not exactly easy for a number of reasons. In addition
to the lack of entry-level content, the rapid pace of change in the Hadoop ecosystem
makes it difficult to keep on top of standards. We find that most discussions
on Hadoop either cover the older interfaces, and are never updated;
or they cover the newer interfaces with little insight into how to bridge the
gap from the old technology. In this book, we’ve taken care to describe the
current interfaces, but we also discuss previous standards, which are still
commonly used in environments where some of the older interfaces are
entrenched.
