----------------------------------

             Summary: Add JavaDocs to MetricConfig
                 Key: FLINK-4302
                 URL: https://issues.apache.org/jira/browse/FLINK-4302
             Project: Flink
          Issue Type: Improvement
          Components: Metrics
    Affects Versions: 1.1.0
            Reporter: Ufuk Celebi


{{MetricConfig}} has no comments at all. If you want to implement a custom reporter and you want to implement its {{open}} method, a {{MetricConfig}} is its argument. It will be helpful to add one class-level JavaDoc stating where the config values are coming from etc.
