> 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?
