> When we create the HiveConf for metastore client, we use a Hadoop Conf as the
> base, which may contain Hive settings in hive-site.xml
> (https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/internal/SharedState.scala#L49).
> However, HiveConf's initialize function basically ignores the base Hadoop
> Conf and always its default values (i.e. settings with non-null default
> values) as the base
> (https://github.com/apache/hive/blob/release-1.2.1/common/src/java/org/apache/hadoop/hive/conf/HiveConf.java#L2687).
> So, even a user put {{javax.jdo.option.ConnectionURL}} in hive-site.xml, it
> is not used and Hive will use its default, which is
> {{jdbc:derby:;databaseName=metastore_db;create=true}}.
