我在猪头写了一个简单的脚本，它在终端运行时运行良好。
但是，当我尝试从浏览器使用Apache服务器运行脚本时，它会引发以下错误。猪的权限被拒绝
[main] ERROR org.apache.pig.tools.grunt.Grunt - You don't have permission to perform the operation. Error from the server: dummy (Permission denied)
[main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2997: Encountered IOException. dummy (Permission denied)
任何想法在哪里解决问题？那么如果它有帮助，我的脚本中没有任何地方使用过任何叫做“哑”的东西！
P.S .:将/ tmp hdfs目录中的权限更改为777，没有帮助！
检查权限在/ tmp本地目录有777，没有问题！
试图用-Dpig.temp.dir在其中阿帕奇有权写的目录中，并没有帮助！
请帮忙，我错过了什么？
编辑：嗯值得一提：当我运行该脚本同时检查猪脚本编制，即猪-c了ScriptName这个错误出现

你能发布完整的堆栈跟踪吗？ –
实际上它的其余部分是常见的或特别是与剧本有关....只有这两行是为什么剧本失败！ – Tanny
