Steve Loughran commented on HADOOP-11447:
-----------------------------------------
Are you confident that things like variance & stddev are never going to raise
errors -or should that string construction be caught & downgraded to a
super.toString()? There's nothing worse than logging triggering strack traces
> Add a more meaningful toString method to SampleStat and MutableStat
> -------------------------------------------------------------------
