>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: metrics

> HADOOP-7734 expressed the desire to support downstream projects that depends on both
0.23+ and 0.20-security releases.
> In order to achieve that we need to evolve the 0.23/trunk API a little to avoid name
conflicts:
> # Rename AbstractMetric to ImmutableMetric, which also address a common question sink
implementer ask about thread safety.
> # Rename MetricsRecord to ImmutableMetrics, ditto.
> # Rename MetricsVisitor to MetricVisitor.
> We better do it before 0.23 is released or, it will be an "incompatible" change.
