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.
