【问题描述】：
我正在尝试执行 bash 脚本，其中包含使用 oozie 的多个 hive 命令。我遇到了几个例外：
- 权限问题 - impersonate oozie job - permission issue - 通过禁用安全性或更改权限来解决
- 找不到文件异常 (org.apache.hadoop.yarn.exceptions.YarnRuntimeException: java.io.FileNotFoundException: 文件不存在: hdfs://:8020/user/hdfs/.staging// job.splitmetainfo) 完整的堆栈跟踪如下所示。
几个事实：
- 我们正在使用hortwonworks 2.0 stack 2.2.6
- 我很确定问题出在 ozzie 作业/配置的某个地方（该脚本在命令行中运行良好）。
我在这里错过了什么？
