类未找到sqoopmain

cloudera社区站
我正在尝试通过Cloudera5.4.x上的oozie运行一个简单的sqoop操作（通过他们的quickstart虚拟机，我想应该正确地预配置它？）
当我通过sqoopcli运行import命令时，一切正常。但是，当我尝试使用oozie工作流（通过hue）运行相同的命令时，它找不到 SqoopMain 班级。

抬起头来 oozie.service.WorkflowAppService.system.libpath 在cloudera manager中，它被设置为 /user/oozie -它附加了 share/lib 不管你在这个领域里做了什么，所以完整的路径是 /usr/oozie/share/lib .
hdfs中的文件夹使用时间戳进行版本控制。-我不确定oozie是如何将这些类添加到类路径的，或者是否需要其他帮助来获取这些类： /user/oozie/share/lib/lib_20150609033900
