If you are already an experienced Java developer then the next step is to grab a download and start playing with Hadoop. You can get either the software from one of the distribution homepages or even a pre-configured VM with everything configured from Cloudera at least, possibly Horton works too.

If you want to understand more of the underlying theory read the original Google papers on MapReduce and the Google File System (GFS) they are quite accessible for academic papers and have become absolute classics.

If you want a fast way to test MapReduce then you can get an idea here with R

My advice is to look at Pig, it worked fine for me and it was simple to configure.
Also, look at what spring has to offer link

Spring hadoop actually is Spring Batch,

It offers a workflow to schedule and run MR, pig, hive and other related technologies jobs

It is not going to help you create MR jobs

Thanks and Regards
