> A useful metric to observe track is compaction count + duration. Since
> compactions are long running and only happen infrequently, the avg/opcount
> stats are should be reset longer than the default polling period (5 sec). In
> addition to 'hbase.period', we should allow a different duration after which
> long-running metrics should expire. This would also fix our existing metrics
> problem where min/max stats are never reset until the process is
> restarted/upgraded.
