[jira] [Commented] (HADOOP-8484) Prevent Configuration getter methods that are passed a default value from throwing RuntimeException

    [ https://issues.apache.org/jira/browse/HADOOP-8484?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13289120#comment-13289120 ] 

Todd Lipcon commented on HADOOP-8484:
-------------------------------------

In general I would prefer to have it crash than to silently ignore an incorrect configuration. Even if a warning is printed, it will end up deep in some logs and probably go un-noticed.

> 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.
