Question

我在猪中写了一个简单的脚本，从终端运行时运行良好。
但是，当我尝试使用apache服务器从浏览器运行脚本时，它会抛出以下错误。

[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)

任何想法解决问题的方法？好吧，如果它有帮助，我的脚本中没有任何地方使用任何名为“虚拟”的东西!!!

P.S。：将/ tmp hdfs目录中的权限更改为777，没有帮助!!
检查/ tmp本地目录中的权限是否有777，没关系!!
试图将-Dpig.temp.dir用于apache有权写入的目录，没有帮助!!
请帮忙，我错过了什么吗？

编辑：值得一提的是：当我在检查猪脚本的编译时运行脚本时出现此错误，即pig -c ScriptName

似乎是apache用户的权限问题在运行以下命令pig -c ScriptName时，检查两个位置的输出。

从壳牌输出
通过Apache服务器执行时从脚本输出

检查日志文件的权限，以及pig尝试写入的位置。这可以帮助您解决此问题。
