解决方法：

在数据库连接的url中添加useSSL=false;2.url中添加useSSL=true，并且提供服务器的验证证书。

jdbc:mysql://localhost:3306/test?useSSL=false

    <property> 
    <name>javax.jdo.option.ConnectionURL</name>  
    <value>jdbc:mysql://master2:3306/metastore?useSSL=false&amp;useUnicode=true&amp;characterEncoding=UTF-8</value>  
    </property>
