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..
For reference:

Thanks,
Puneet

"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

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). I had answered
a similar question<http://stackoverflow.com/questions/17090022/hive-query-control-flow/17095756?noredirect=1#comment24873979_17095756>
few days ago on SO, you might find it helpful. 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.

HTH

Warm Regards,
Tariq

Hi Folks,

I am new to hive and need information, tutorials etc that you can point to. 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.

Thanks,
Bharati
