对于在oozie里放置Mysql驱动包的总结
根据网上的参考以及我个人经验安装的使用
（1）放一份到$OOZIE_HOME/libext下 （是 mysql-connector-java-5.1.21.jar）（这里放到bigdatamaster节点）
（2）放一份到$OOZIE_HOME/lib下 （是 mysql-connector-java-5.1.21.jar）（这里放到bigdatamaster节点）
（3）放一份到/usr/share/java/下（一定要重命名，mv mysql-connector-java-5.1.21-bin.jar mysql-connector-java.jar）（这里放到bigdatamaster节点）
（4）放一份到$JAVA_HOME/jre/lib/ext （是 mysql-connector-java-5.1.21.jar）（这里放到bigdatamaster节点、bigdataslave1节点和bigdataslave2节点）
（5）放一份到$OOZIE_HOME/oozie-server/lib下 （是 mysql-connector-java-5.1.21.jar）（这里放到bigdatamaster节点）
（1）放一份到$OOZIE_HOME/libext下

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)

（4）因为，我暂时用的是jdk1.7。 即，在$OOZIE_HOME/libext下的mysql-connector-java-6.0.3.jar 替换成 mysql-connector-java-5.1.21.jar 。
（5）放一份到$OOZIE_HOME/oozie-server/lib下 （是 mysql-connector-java-5.1.21.jar）（这里放到bigdatamaster节点）
