             Summary: Backport to branch-1 HBASE-9774 HBase native metrics and metric collection for coprocessors
                 Key: HBASE-18060
                 URL: https://issues.apache.org/jira/browse/HBASE-18060
             Project: HBase
          Issue Type: New Feature
    Affects Versions: 1.4.0, 1.3.2, 1.5.0
            Reporter: Vincent Poon
            Assignee: Vincent Poon


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
- 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
