Granted, the text explains certain restrictions. The crucial one is having lots of RAM because processing is done in memory. This avoids having the processing needing to often write to disk. The latter implies slower and the need for large disks.
Several of the book's examples involve standard SQL. No accident. Impala lets you leverage your expertise in SQL. So there are the familiar commands DROP TABLE, DESCRIBE, SELECT and so on.
To be sure, there are indeed HDFS specific commands and some examples walk you through those.
Overall, I would recommend that you already also know Hadoop and the Amazon Web Services. Given that Impala resides on top of Hadoop, it improves what you can get out of the book.
Learning Cloudera Impala by Avkash Chauhan is a book that I wanted to like, but couldn't really get into.
In addition to numerous errors that I noticed, for me the text didn't flow well and it took me longer to read than it should have because of this. I believe that the author knows how to use and implement Impala, but he had wasn't able to convey that to me in a way that I felt I was learning something. The book is also light on examples showing how the technology can be used to accomplish the task at hand.
I know that Impala is a newer technology and more books will come out covering it, until then I think that reading the online documenation is just as good a bet as reading this book.
I unfortunately can't even recommend this book as a reference as there are too many places that the author sends you to the web to learn more about a topic that he has covered at a very high level.
Maybe I missed the point of this book, but too me it falls short.
