>             Project: Spark
>          Issue Type: Sub-task

>    Affects Versions: 1.5.0

> _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._
