Question

Currenly我设置了11个节点的Hadoop集群（CDH5），所有服务都在资源管理器和所有其他节点上运行良好。我正在使用字数统计程序测试集群，以确保它正常工作。

一开始，我收到了一个权限被拒绝的错误，因为它无法运行mapper.py，有人建议将mapper.py和reducer.py移动到/ tmp，其中每个人都有执行权限。看起来我不再获得权限被拒绝错误，但显示的错误一直显示。

任何线索或建议我应该做些什么来完成这个，我跟着日志没有什么不同于此错误消息

Answer 1

“没有此类文件或目录”错误表明/tmp/mapper.py不存在。由于文件位于/tmp，因此可能已被临时清除cron作业删除，可能是通过重新启动系统或执行rm /tmp/*的人。

Answer 2

尝试

-file /tmp/mapper.py -file /tmp/reducer.py

运送文件。 Arg -files 可能正在查看hdfs

Hadoop Streaming作业失败“Python”
