Hi, There are many online tutorials and blogs to provide quick get-set-go sort of information. To start with you can learn Hadoop. For detailed knowledge you will have to go through e-books as mentioned by Lefty. These books are bulky but will provide every bit of hadoop.
I recently came across an android app called 'Big data Xpert', which has tips and tricks about big data technologies. I think that it can be quick and good reference for beginners as well as experienced developers..

"Programming Hive" and "Hadoop: The Definitive Guide" are available at the O'Reilly website (http://oreilly.com/) and on Amazon. But don't forget the Hive wiki: * Hive Home -- https://cwiki.apache.org/confluence/display/Hive/Home * Getting Started -- https://cwiki.apache.org/confluence/display/Hive/GettingStarted * Hive Tutorial -- https://cwiki.apache.org/confluence/display/Hive/Tutorial - Lefty On Wed, Jun 19, 2013 at 7:02 PM, Mohammad Tariq <donta...@gmail.com<mailto:donta...@gmail.com>> wrote: Hello ma'am, Hive queries are parsed using ANTLR<http://www.antlr.org/> and and are converted into corresponding MR jobs(actually a lot of things happen under the hood).

But I would suggest you to go through the original paper<http://cs.brown.edu/courses/cs227/papers/hive.pdf> which explains all these things in proper detail. I would also recommend you to go through the book "Programming Hive". It's really nice.

I have installed hive to work with MySQL. I can run queries. Now I would like to understand how the map and reduce classes are created and how I can look at the data for the map job and map class the hive query generates. Also is there a way to create custom map classes. I would appreciate if anyone can help me get started.
