> Multiple other apache components allow sending metrics over to Hadoop2
> metrics, which allow for monitoring solutions like Ambari Metrics Server to
> work against that to show metrics for components in one place. Our Codahale
> metrics works very well, so ideally, we would like to bridge the two, to
> allow Codahale to add a Hadoop2 reporter that enables us to continue to use
> Codahale metrics (i.e. not write another custom metrics impl) but report
> using Hadoop2.
> Apache Phoenix also had such a recent usecase and were in the process of
> adding in a stub piece that allows this forwarding. We should use the same
> reporter to minimize redundancy while pushing metrics to a centralized
> solution like Hadoop2 Metrics/AMS.
