> Passing a negative value to the interval field of MetricsRegistry#newQuantiles should throw a MetricsException with a clear error message. The current stack trace looks something like:
> java.lang.IllegalArgumentException: null
> at java.util.concurrent.ScheduledThreadPoolExecutor.scheduleAtFixedRate(ScheduledThreadPoolExecutor.java:420)
> at org.apache.hadoop.metrics2.lib.MutableQuantiles.<init>(MutableQuantiles.java:107)
> at org.apache.hadoop.metrics2.lib.MetricsRegistry.newQuantiles(MetricsRegistry.java:200)
> Along similar lines, should the other methods like MetricsRegistry#newCounter() also have parameter checking for negative int/long values?
