Yes we originally wanted to try and use the Hadoop Timeline Server for storm
metrics feedback to nimbus + UI + history like server. But it was not stable
at the time, so we stopped. For the sake of playing nicely with the rest of
the big data ecosystem I would like to see us support it as an option for
metrics collection/query, but until the timeline server v2 is ready and
released. For me the important thing is that we have a decent time series DB
that comes with storm by default and is pluggable so we can replace it with
something else that has similar capabilities in the future.

It's actually in Phase 2 of porting JStorm, but I'm absolutely ok to
discuss this in advance.
