bq. Hi Juhani,
bq.
bq. Thanks for the feedback. This appears in the diff because I rebased
the patch on trunk (sorry, I may have forgotten to mention this). Please see :
https://github.com/apache/flume/blob/trunk/pom.xml(lines 41 to 46). Thats the
reason you see it as added when you diff between patch versions 4 and 6. This
patch should be applied to trunk.
right, my bad!
Everything looks good to me with the addition of the other memory channel. I'll
check over individual components as soon as this is committed

> Core configuration component

>
> Key: FLUME-1052
> URL: https://issues.apache.org/jira/browse/FLUME-1052
> Project: Flume
> Issue Type: Sub-task
> Affects Versions: v1.0.0
> Reporter: Hari Shreedharan
> Assignee: Hari Shreedharan
> Fix For: v1.2.0
>
> Attachments: FLUME-1052-2.patch
>
>
> Currently the configuration provider implementation encompasses all the
> syntactic and structural validation rules for loading the configuration.
> Externalizing this functionality to a library will allow external tools to
> easily operate on flume configuration files and be able to help parse and
> validate these files.
> 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.
> Provide abstract Configuration stubs for each component type, sources,
> channels, sinks, selectors etc, which are in the new package, independent on
> ng-core. Now for each of the channels extend the abstract class and check the
> config properties for each of the required parameters for that component, for
> example: MultiplexingChannelSelectorConfigurator would look for default
> channel etc. If a particular component does not have a configuration class
> then let the current mechanism continue.
> This will require implementation for each component, but it should not be too
> complex. One additional advantage we get from this is that we can separate
> out the config validation from the components into these stubs, but we will
> still need to read the values out of the Context as we do currently(else we
> end up making the configuration dependent on flume-ng-core itself which we
> wanted to avoid).
> A problem with this is making a change to the configuration would require
> changes in the configuration classes and in the components also(where the
> configuration is read and the component is actually configured). I could not
> figure out a way of avoiding this.
