> Many moons ago, in one of the HUG talk for Chukwa, one user ask if it is possible to create a splitter interface for Chukwa Collector for monitoring data at near real time.  The answer was possible, but there was no code to show this capabilities.  Over the Xmas holidays, I decided to take on this task and write something simple to show how this is done.
> The idea is to reuse existing Chukwa Collector with PipelineStageWriter coupled with SocketTeeWriter for data stream split.  By adding a SocketDataLoader inside HICC to act as data stream subscriber and extract client trace information to render on the browser.  Hence, the additional pipeline looks like this:
> Adaptor -> Agent -> Collector -> SocketTeeWriter <- Socket Data Loader <- HICC
