This book didn't age very well, most of the technologies described in the book are obsolete already.
I needed to quickly learn Hadoop fundamentals:HDFS and HBase. As a classically trained engineer I went for the book from the reputable issuer with most positive reviews.
Although the chapters on Hadoop architecture, HBase, Avro and HBase were very helpful to get me started with all technologies I needed, the rest of the book is unbelievably outdated.
Multiple pages of Java code listings, guides to install lots of applications (depending on what OS you're using) by hand.
No one does that anymore due to 2 reasons:
- Docker helped me to install Hadoop on my Windows laptop that's running Debian</>
- Code suitable for the latest Hadoop build is available on Github </ol>
Even though I truly believe that I was able to learn substantially more from the book than what I needed, I found most topics covered pretty well on a dated Udemy course. However, I spent hours on Udemy and days to finish the book.
My score 1/5
