Subject [jira] [Created] (HADOOP-7956) Remove duplicate definition of default config values
Date Wed, 04 Jan 2012 20:13:40 GMT
Remove duplicate definition of default config values

                 Key: HADOOP-7956
                 URL: https://issues.apache.org/jira/browse/HADOOP-7956
             Project: Hadoop Common
          Issue Type: Improvement
          Components: conf
            Reporter: Eli Collins

We define default configuration values in two places:
#1 The default.xml files (eg core-default.xml)
#2 The _DEFAULT defines in *Keys.java

This means the defaults used in the code may or may not be dead code based on whether the
config is present in the default xml file. Would be good to define these in one place. Eg:
#1 Just have the defines in the code and figure out how to make those accessible as a loadable
resource (eg could generate the default files from the defines in the KeysPublic* files)
#2 Remove one of the definitions entirely (possible to live w/o the default files?) or
#3 Remove the overlap between the code and default files
