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

             Summary: A few problems in ParquetRelation.enableLogForwarding()
                 Key: SPARK-8122
                 URL: https://issues.apache.org/jira/browse/SPARK-8122
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.5.0
            Reporter: Konstantin Shaposhnikov


_enableLogForwarding()_ should be updated after parquet 1.7.0 update , because name of the logger has been changed to `org.apache.parquet`. From parquet-mr Log:

{code}
    // add a default handler in case there is none
    Logger logger = Logger.getLogger(Log.class.getPackage().getName());
{code}

Another problem with _enableLogForwarding()_ is that it doesn't hold to the created loggers that can be garbage collected and all configuration changes will be gone. From https://docs.oracle.com/javase/6/docs/api/java/util/logging/Logger.html javadocs:  _It is important to note that the Logger returned by one of the getLogger factory methods may be garbage collected at any time if a strong reference to the Logger is not kept._
