我正在尝试执行bash脚本，它包含使用oozie的多个配置单元命令。我遇到了几个例外：
权限问题-模拟oozie作业-权限问题-通过禁用安全性或更改权限来解决
文件未找到异常（org.apache.hadoop.yarn.exceptions.yarnruntimeexception:java.io.filenotfoundexception:文件不存在：hdfs://：8020/user/hdfs/.staging//job.splitmetainfo）完整堆栈跟踪显示如下。
两个事实：
我们使用的是HortwnWorks 2.0堆栈2.2.6
我很确定问题出在ozzie作业/配置的某个地方（脚本在命令行中运行良好）。
我错过了什么？

请告知。
