> in o.a.h.hdfs.server.namenode.metrics.NameNodeMetrics.java, metrics are declared as follows:
> {code}
>   @Metric("Duration in SafeMode at startup") MutableGaugeInt safeModeTime;
>   @Metric("Time loading FS Image at startup") MutableGaugeInt fsImageLoadTime;
> {code}
> Since some users may confuse which unit (sec or msec) is correct, they should be documented.
