I am working on a case study on Hadoop for my college project. I would appreciate if anyone could please point me to resources that would provide information on the following:

1. Development methodology
     - What development models are used?
     - How are changes from the community reviewed and integrated?
     - How are requirements gathered and who evaluates/prioritizes them?
     - How is work distributed and timelines enforced?

2. Hadoop Objectives:
    - Technical
    - Political
    - Financial
