我想在豬教程運行裸露的骨頭基本的腳本（http://pig.apache.org/docs/r0.11.1/start.html#pig-scripts），看起來像這樣：阿帕奇豬 - 錯誤6007：無法檢查名稱
/* myscript.pig
My script is simple.
It includes three Pig Latin statements.
*/
A = LOAD 'student' USING PigStorage() AS (name:chararray, age:int, gpa:float); -- loading data
B = FOREACH A GENERATE name; -- transforming data
DUMP B; -- retrieving results
輸出：

macbook-3:pig myusername$ cat /Volumes/Nimue/Environment/pig-0.11.1/pig_1368473213767.log
