------------------------------------
Summary: Prevent Configuration getter methods that are passed a
default value from throwing RuntimeException
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.
