Ahmed Radwan commented on HADOOP-8484:
--------------------------------------
The only issue I have is that there are cases where it is helpful for it to
crash to alarm for the incorrect configuration and there are cases where
picking the default is just appropriate and will enhance the fault-tolerance.
But I agree with you, the generalization here in Configuration may not be the
right choice, and it is better to handle this on a case-by-case basis, so the
code reading the property can decide to catch the exception if needed. I am
closing this one.

> Key: HADOOP-8484
> URL: https://issues.apache.org/jira/browse/HADOOP-8484
> Project: Hadoop Common
> Issue Type: Bug
> Components: conf
> Affects Versions: 2.0.0-alpha
> Reporter: Ahmed Radwan
> Fix For: 2.0.1-alpha
>
>
> Configuration getter methods that are passed default values can throw
> RuntimeExceptions if the value provided is invalid (e.g.
> NumberFormatException).
> In many cases such exception results in more serious consequences (failure to
> sart a service, see for example NodeManager DeletionService). This can be
> avoided by returning the default value and just printing a warning message.
