解决办法
很多人刚开始安装oozie时，这个错误经常碰到，网上很多博客都没有提及到这点如何去解决。

只是单纯的认为，只需将 mysql-connector-java-5.1.21.jar放在$OOZIE_HOME/libext下即可。
其实啊，这还没操作完呢，还需放一份到$OOZIE_HOME/lib下

同事啊，这个报错很常见，原以为把mysql-connector-java-*-bin.jar丢到oozie的lib即可，但是发现依然宝盖错误。后来在网上找到需要将这个包放到这个路径下就通过了(名字需要修改下)

因为，我暂时用的是jdk1.7。 即，在$OOZIE_HOME/libext下的mysql-connector-java-6.0.3.jar 替换成 mysql-connector-java-5.1.21.jar 。
