我在尝试执行shell脚本时遇到以下错误。如果我在这里犯了什么错误，请告诉我。
我已将所有文件复制到hdfs中。oozie文件夹包含scripts文件夹，我在该文件夹中有sample.sh。

Cannot run program "sample.sh" (in directory "/var/lib/hadoop-yarn/cache/yarn/nm-local-dir/usercache/cloudera/appcache/application_1468541187565_0011/container_1468541187565_0011_01_000002"): error=2, No such file or directory

请找到我的工作和工作流程文件。
