ClassNotFound SqoopMain

我正在尝试在Cloudera 5.4.x上通过Oozie运行一个简单的Sqoop Action（通过他们的QuickStart VM，我应该正确预配置？）

当我通过Sqoop CLI运行导入命令时，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，它无法找到SqoopMain类。

在cloudera管理器中查找oozie.service.WorkflowAppService.system.libpath，并将其设置为/user/oozie - 它将share/lib附加到您在此字段中放置的任何内容，因此完整路径为{{1 }}

HDFS中的文件夹带有时间戳版本。 - 我不确定oozie如何将这些类添加到类路径中，或者如果它需要额外的帮助来选择它：/usr/oozie/share/lib

Answer 1

事实证明，您需要提供job.properties oozie.use.system.libpath=true

将它放在workflow.xml中似乎不起作用。

基本上，我现在拥有的是没有配置的裸sqoop动作和job.properties我需要的所有属性。
