Subject [jira] Created: (HADOOP-6578) Configuration should trim whitespace around class name values
Date Fri, 19 Feb 2010 22:26:27 GMT
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.
