Re: [jira] [Commented] (FLUME-1522) System hook before initialization of all components
Hi Rink. It would be helpful if you guys could outline what you are trying
to achieve at a higher level.

The kind of helpful explanation that would assist with the communication is
something along the lines of a Use Case or a User Story. You guys are
saying "what", while I am asking "why?".

If you could give a clear example of how and why you want some type of
system initialization hook, what you plan to use it for, and what it will
allow you to achieve, we can all understand and empathize with your problem
and work together to solve it.

>From my perspective, I want to help maintain Flume as a loosely coupled
system (the current primitives of Sources, Channels and Sinks are loosely
coupled and independently interchangeable) while adding capabilities and
features to ensure it is the best data collection system available. I hope
this makes sense and clarifies my intentions.

Regards,
Mike
