使用Hue通过Shell脚本在oozie中调度sqoop作业

Question

我可以使用Hue在Oozie中运行sqoop命令。但是，当我尝试通过将它放在shell脚本中运行相同的sqoop命令时，我收到如下错误

Stdoutput 2016-05-20 10:52:13,241 ERROR [main] sqoop.Sqoop (Sqoop.java:runSqoop(181)) - Got exception running Sqoop: 

java.lang.RuntimeException: Could not load db driver class: oracle.jdbc.OracleDriver

我已经包含了jdbc jar文件，就像我直接运行sqoop命令一样。我不明白为什么它不适用于shell脚本。

这是Hue生成的工作流程
