Eric Yang updated CHUKWA-441:
-----------------------------
Status: Patch Available (was: Open)
Real time hadoop activity monitor. This feature only works for single
collector, to make this work on large scale cluster, the data needs to be
channeled to a single collector.
> Real time hadoop activity monitoring capabilities via Client Trace Logs

> 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
