I agree that the Spark official documentation is pretty good. However, a book also serves a useful purpose. It provides a structured roadmap for learning a new technology. Everything is nicely organized for the reader. For somebody who has just started learning Spark, the amount of material on the Internet can be overwhelming. There are ton of blogs and presentations on the Internet. A beginner could easily spend months reading them and still be lost. If you are experienced, it is easy to figure out what to read and what to skip.
I also agree that a book becomes outdated at some point, but not right away. For example, a book covering DataFrames and Spark ML is not outdated yet.

I would like to suggest learn it from several ways as bellow: * spark official document, trust me, you will go through this for several time if you want to learn in well : http://spark.apache.org/ * spark summit, lots of videos and slide, high quality : https://spark-summit.org/ * databricks' blog : https://databricks.com/blog * attend spark meetup : http://www.meetup.com/ * try spark 3-party package if needed and convenient : http://spark-packages.org/ * and I just start to blog my spark learning memo on my blog: http://litaotao.github.io in a word, I think the best way to learn it is official document + databricks blog + others' blog ===>>> your blog [ tutorial by you or just memo for your learning ] On Mon, Feb 29, 2016 at 4:50 PM, Ashok Kumar <ashok34...@yahoo.com.invalid<mailto:ashok34...@yahoo.com.invalid>> wrote: Thank you all for valuable advice.
