我犯了个错误 Unable to open iterator for alias 对于一个简单的 LOAD 以及 DUMP 清管器操作。我已经看了下面的答案：
错误1066:无法打开别名-pig的迭代器
但他们帮不了我。
我的环境：

OS: Windows 7
Pig version: 0.13.0
Mode: Local

它在错误中显示异常是由于未能更改tmp目录中某个文件的权限而导致的。但是当我检查tmp目录时，没有这样的文件（可能是在命令完成后被删除的？）。

DUMP a;

load语句的语法有什么错误吗？除了java和java\u home之外，还有其他环境变量需要特别设置吗？
