> I'm studying flushing and blocking memstores. I came across the MBean
> Hadoop:service=HBase,sub=Memory,name=RegionServer It looks promising with
> metrics on blocked flush time, etc. See below. All metrics are zero. I tried
> to get it going. It is connected to the heap tuner facitlity that we might
> want to turn on. I managed to get the latter going w/ below configs.... (need
> to dump out more on what this thing is doing because it is tricky enabling it)
> {code:java}
> <configuration>
> <property>
> <name>

> We should make this bean work whether tuning is on or off or remove it.
