Hadoop For Dummies (For Dummies (Computers))

I was looking for an introduction to Hadoop, to understand where my engineers were talking about. This book did the job !

I have skim through this book to see if there are new things in the book for me. I have not yet tried the examples like the first reviewer during this first round of reading but wanted to have a feel for the book and I will try all the examples during my second round of reading this book and I will definitely roll up my sleeve and try all the examples. I will recommend this book for anyone who is new to Hadoop and also for the advance Hadoop engineers if you want to come up to speed on the latest in Hadoop . The book is well organized and very easy to read and follow. You will learn new things from this book and you will bring yourself up to speed on Hadoop versions 1.x and 2.x and the differences between the two versions.*********During my second round of reading and trying out the example I will agree with the first reviewer that some of the examples did not work and you have to spend a lot of time figuring how to get them to work. Also you have to be very good with Linux/unix to figure out the examples and get them to work which is the case with learning and using Hadoop any ways. However, the book is still very good book to read and learn about Hadoop even for non technical folks by skipping the example sections. The fact that the book is well organized, easy to read with lots of information about Big Data (minus the examples that do not work) I will still give it a five star.

good book, very helpful and easy to follow

Very informative. Well written.

You'd think a tech book that uses a VM download to set the environment correctly would have examples that worked. Not this one. In example after example the code does not work. Good idea. Really poor execution. To use these examples you will be Google-hacking over and over. Also, the authors seem to never have taught anyone before: for example, they don't provide simple instructions to shut down the VM and save the state, they use different syntax style from chapter to chapter and when they start a new example they don't provide basic instructions on how to get right to the example. They just don't think through what a tutorial needs to do for 'Dummies'. Another example, in chapter 6 they introduce a "Flights by Carrier" example. It is needs to be setup on the VM you downloaded earlier. The VM gives everyone the same environment with the same directory structure. They tell introductory readers to "go to your directory with your Java code and compile it using the following command". Someone more familiar with training users would have listed the command to "go to the directory with your Java code". Readers not familiar with the Linux VM will be hacking around for a while in order to get there. For an intro book, this is just not acceptable. They make mistakes like this over and over.

Awesome book. Very easy to read and understand.I understand Hadoop much better now and It may have landed me a job.Thank so much Dirk.

Great intro to the technology and the community. It helped me target the further reading and resources I need to stand up a working environment. Great job!

These are fine and just what I needed for some of my data science projects. Good quality and good deal for the money!

good explanations... but the bad reviews about the examples are very true. You'll need to be very patient google'ling linux commands to get the examples working... hint #1:.... p.50 you'll likely need to change the permissions of a hadoop temp directory using: "sudo -u hdfs hadoop fs -chmod -R 777 /tmp/hadoop-yarn". Also the code examples are not where they claim to be (http://www.dummies.com/extras/hadoop) but actually found here: http://eu.wiley.com/WileyCDA/WileyTitle/productCd-1118607554.html. Strongly recommend watching this guys video's on Hadoop for a kick start before reading this book Youtube.com/watch?v=DLutRT6K2rM (will help make more a little more sense)

Excellent. Easy to follow and very well written.

I usually don't give reviews but this time I felt compelled to give it. I read the reviews that programmes etc dont work but I also read from author's feedback that they have corrected them and can be downloaded from their website. So I bought into the argument and went for it. However I am horrified to mention that I could not get to set up the virtual machine, because installer could not find 4 of the packages and that should have happened automatically. I must mention that I am an experienced IT professional with very good expertise in Linux, Java etc but I simply dont have the time to figure out how to resolve this problem. I am a dummy when it comes to hadoop and so I expect a book like this one will give me a head start before I buy more advance books etc. So please do not waste your money and time on this book unless you are an adventurer kind!!

I just like this book as its easy to learn and understand by the graphs and pictures. The book was totally good and thanks to Amazon and got a good book

Very well written. However, attempts to promote IBM and non-open source stuffs are apparent in the entire book. The authors are from IBM. Otherwise, a very good book for starters in Hadoop.
