Re: Metrics in 0.96
Hi Andy,

Yes, that is exactly the plan. I am sure we have areas where we simply lack metrics, I have noted this down somewhere and will dig up the details. It would also consolidate (and close out) all open "Improve HBase Metrics" JIRAs.

This includes switching to Hadoop Metrics v2 and adding all missing stats, as well as fixing those that are misleading or useless. For that reason I talked to our friends at Sematext during the Buzzwords HBase workshop, as well as to our internal HBase team. We all seem to agree and I'd be happy to setup some sort of call/task force to discuss what we need to work on etc. Obviously I would love for someone from the FB team to also partake as they have done heaps lately on that end - but I also understand if that is a timing issue.
