There's no way to remove a property from a Configuration
--------------------------------------------------------

                 Key: HADOOP-6948
                 URL: https://issues.apache.org/jira/browse/HADOOP-6948
             Project: Hadoop Common
          Issue Type: Improvement
          Components: conf
    Affects Versions: 0.21.0, 0.20.2
         Environment: all
            Reporter: Mike Baranczak
            Priority: Minor


The Configuration class has a lot of methods for setting properties, but it's impossible to
remove a property once it's set. Trying to set it to null results in a NullPointerException,
since java.util.Properties doesn't allow null values. When building a Configuration programmatically,
this can be a problem.
