> In the patch ofÂ
> [HIVE-12020|https://issues.apache.org/jira/browse/HIVE-12020], we changed the
> DataNucleus related logging configuration from nine fine-grained loggers with
> three coarse-grained loggers (DataNucleus, Datastore and JPOX). As Prasanth
> Jayachandran
> [explain|https://issues.apache.org/jira/browse/HIVE-12020?focusedCommentId=15025612&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15025612],
> these three loggers are the top-level logger in DataNucleus, so that we
> don't need to specify other loggers for DataNucleus. However, according to
> the
> [documents|http://www.datanucleus.org/products/accessplatform/logging.html]
> and [source
> codes|https://github.com/datanucleus/datanucleus-core/blob/master/src/main/java/org/datanucleus/util/NucleusLogger.java#L108]
> of DataNucleus, the top-level logger in DataNucleus is `DataNucleus`.
> Therefore, we just need to keep the right one.
