解决办法：修改conf/hive-site.xml为（即去掉头2行）：
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:derby:;databaseName=metastore_db;create=true</value>
</property>
<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>org.apache.derby.jdbc.EmbeddedDriver</value>
</property>
<property>
<name>hive.metastore.local</name>
<value>true</value>
</property>
<property>
<name>hive.metastore.warehouse.dir</name>
<value>file:///root/training/apache-hive-2.3.0-bin/warehouse</value>
</property>
</configuration>
