Review request for Flume.
Changes
-------
Updated licenses.
Summary
-------
Currently the configuration of each component sits deep inside the component
themselves. There is no way to verify if a configuration is valid before run
time. In most systems like Flume, it is likely that these confs will be
deployed from one single host, on to the machines where flume agents are
running. Only when each agent starts, invalid confs are identified because the
Agents would terminate by throwing exceptions. This is a first attempt to make
a component-aware configuration system which is independent of the Flume, and
does not require the Flume jar to be installed. Each component needs a
configuration manager, which configures the components.
I have not completed the validation part yet, but have completed the
configuration managers for all the components that come in the flume jar. I
will add support for the other components, such as HDFS sink, JDBC channel etc
soon. I will also add the validation support to the classes, but would like a
review of the model being proposed here.
Note that I do know of a couple of bugs in the existing diff(like that if the
name of a config key starts with an Upper case letter, an exception is thrown)
- I will fix and upload the review here soon.
This addresses bug FLUME-992.

Testing
-------
All existing unit tests for the components whose configuration has now been
moved to these stubs pass.
Thanks,
