[jira] Created: (HADOOP-6578) Configuration should trim whitespace around class name values

Configuration should trim whitespace around class name values
-------------------------------------------------------------

                 Key: HADOOP-6578
                 URL: https://issues.apache.org/jira/browse/HADOOP-6578
             Project: Hadoop Common
          Issue Type: Improvement
          Components: conf
    Affects Versions: 0.22.0
            Reporter: Todd Lipcon
            Priority: Minor


I've seen multiple users make an error where they've listed some whitespace around a class name (eg for configuring a scheduler). This results in a ClassNotFoundException which is very hard to debug, as you don't notice the whitespace in the exception! We should simply trim the whitespace in Configuration.getClass and Configuration.getClasses to avoid this class of user error.
