Subject Hadoop documentation: control flow and FSM diagrams
Date Fri, 28 Mar 2014 16:58:40 GMT
Hi All,

I have created a wiki on github:


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
- 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.
