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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
