[jira] [Created] (HADOOP-15015) TestConfigurationFieldsBase to use SLF4J for logging

Steve Loughran created HADOOP-15015:
---------------------------------------

             Summary: TestConfigurationFieldsBase to use SLF4J for logging
                 Key: HADOOP-15015
                 URL: https://issues.apache.org/jira/browse/HADOOP-15015
             Project: Hadoop Common
          Issue Type: Bug
          Components: conf, test
    Affects Versions: 3.0.0
            Reporter: Steve Loughran


{{TestConfigurationFieldsBase}} has a protected "configDebug" field used to turn logging on/off

{code}
      if (configDebug) {
        System.out.println("Field: " + f);
      }
{code}

Presumably its there to allow people with code access to debug their classes. But if we switch to SLF4J you get controllable logging @ runtime.
