Hive默认是采用Derby来存储其Meta信息的，如下：
<property>
 
<name>javax.jdo.OPTION.ConnectionURL</name>
 
<value>jdbc:derby://zw-hadoop-master:1527/metastore_db;create=true</value>
 
<description>JDBC connect string FOR a JDBC metastore</description>
 
</property>
 
 
<property>
 
<name>javax.jdo.OPTION.ConnectionDriverName</name>
 
<value>org.apache.derby.jdbc.ClientDriver</value>
 
<description>Driver class name FOR a JDBC metastore</description>
 
</property>
