豬的權限被拒絕

Question

我在豬頭寫了一個簡單的腳本，它在終端運行時運行良好。
但是，當我嘗試從瀏覽器使用Apache服務器運行腳本時，它會引發以下錯誤。

[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) 

任何想法在哪裏解決問題？那麼如果它有幫助，我的腳本中沒有任何地方使用過任何叫做「啞」的東西！

P.S .:將/ tmp hdfs目錄中的權限更改爲777，沒有幫助！
                 檢查權限在/ tmp本地目錄有777，沒有問題！
                 試圖用-Dpig.temp.dir在其中阿帕奇有權寫的目錄中，並沒有幫助！
請幫忙，我錯過了什麼？

編輯：嗯值得一提：當我運行該腳本同時檢查豬腳本編制，即豬-c了ScriptName這個錯誤出現

Answer 1

這似乎是權限問題了apache用戶。
運行以下命令pig -c ScriptName時，請檢查兩個位置的輸出。

同時通過Apache服務器

執行

1. 輸出殼牌
2. 輸出腳本檢查日誌文件的權限，以及，其中豬正在嘗試寫。這應該可以幫助你解決這個問題。
