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. - Bobby
