> I'd like to explore backporting HBASE-9774 to branch-1, as the ability for coprocessors
to report custom metrics through HBase is useful for us, and if we have coprocessors use the
native API, a re-write won't be necessary after an upgrade to 2.0.
> The main issues I see so far are:
> - the usage of Java 8 language features.  Seems we can work around this as most of it
is syntactic sugar.  Will need to find a backport for LongAdder
> - dropwizard 3.1.2 in Master.  branch-1 is still on yammer metrics 2.2.  Not sure if
these can coexist just for this feature
