There is a coding tutorial available at this link in the middle of the page: http://www.greenplum.com/resources/mapreduce/

Key things to note about Greenplum’s MR implementation:
- It’s very similar in form and expression to Google and Hadoop
- Extensions for Joins and Pipelined task execution
- Native parallel file access
- Parallelism is full and transparent to the programmer

In summary: we have implemented MapReduce within which you can write SQL, Perl, Python and many more languages. It is straightforward use MR programs written for Hadoop or Google and port them to Greenplum.

Google’s work is seminal in that they woke the world up to the benefits of this old idea.

Google’s paper wasn’t seminal. “MapReduce” is 30 years old. Did you read the paper? Nothing ground-breaking.

The only thing Google did was write the code. However, in my opinion that’s high praise–talk is cheap. Google writes code; everybody else daydreams.
