Oozie无法通过Cloudera Manager创建MySQL数据库：java.lang.ClassNotFoundException：com.mysql.jdbc.Driver

Question

这让我完全难住。我在Amazon EC2 Ubuntu实例上使用Cloudera Manager来启动Oozie w/MySQL。我尝试阅读关于jdbc和MySQL的所有其他问题，并在过去两天尝试了很多方法来尝试完成此设置，但仍然失败。每一个。时间。

我试过把mysql-connector-java-5.1.25-bin.jar添加到oozie和java的每个/ lib /文件夹中。这是在以下位置：

/home/oozie_lib/oozie-workflows/lib/mysql-connector-java-5.1.25-bin.jar 
/usr/lib/jvm/java-6-openjdk-amd64/jre/lib/mysql-connector-java-5.1.25-bin.jar 
/usr/lib/hive/lib/mysql-connector-java-5.1.25-bin.jar 
/usr/lib/oozie/lib/mysql-connector-java-5.1.25-bin.jar 
/usr/share/java/mysql-connector-java-5.1.25-bin.jar 

然而，当我试图创建使用Cloudera的经理在Oozie的一个新的数据库，我碰到了以下内容：

Error: Could not connect to the database: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver 

Stack trace for the error was (for debug purposes):

这是我的/ etc /环境：

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" 
JAVA_HOME="/usr/lib/jvm/java-6-openjdk-amd64/jre" 
CLASSPATH="/usr/lib/jvm/java-6-openjdk-amd64/jre/lib:." 

任何提示/指示什么地方从哪里去？

我知道这是太晚每OQ.For未来用户，

我有一个类似的问题（异常在VALIDATE DB步骤）和我的错误是附加在oozie.service.JPAService的空间。 jdbc.driver财产/etc/oozie/conf/oozie-site.xml

<value>com.mysql.jdbc.Driver </value> 

更正为，

<value>com.mysql.jdbc.Driver</value>
