Hi All, I have created a wiki on github:
https://github.com/ercoppa/HadoopDiagrams/wiki This is an effort to provide an updated documentation of how the internals of Hadoop work. The main idea is to help the user understand the "big picture" without removing too much internal details. You can find several diagrams (e.g. Finite State Machine and control flow). They are based on Hadoop 2.3.0. Notice that: - they are not specified in any formal language (e.g., UML) but they should easy to understand (Do you agree?) - they cover only some aspects of Hadoop but I am improving them day after day - they are not always correct but I am trying to fix errors, remove ambiguities, etc I hope this can be helpful to somebody out there. Any feedback from you may be valuable for me. Emilio.
