Allen Wittenauer reopened HADOOP-6228: -------------------------------------- argh wrong jira. > Configuration should allow storage of null values. > -------------------------------------------------- > > Key: HADOOP-6228 > URL: https://issues.apache.org/jira/browse/HADOOP-6228 > Project: Hadoop Common > Issue Type: Bug > Components: conf > Reporter: Hemanth Yamijala > > Currently the configuration class does not allow null keys and values. Null > keys don't make sense, but null values may have semantic meaning for some > features. Not storing these values in configuration causes some arguable side > effects. For instance, if a value is defined in defaults, but wants to be > disabled in site configuration by setting it to null, there's no way to do > this currently. Also, no track of keys with null values is recorded. Hence, > tools like dump configuration (HADOOP-6184) would not display these > properties. > Does this seem like a sensible use case ? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
