> In the patch of  [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.
