Hadoop群集中的mrjob virtualenv錯誤：權限被拒絕

Question

我在一個擁有Hadoop集群的大型企業組織中工作。 我得到了管理員在所有Hadoop工作節點上安裝virtualenv mrjob以便我可以提交具有工作節點上可能不存在的標准Python依賴關系的mrjob 。 根據此處的文檔，這就是我的mrjob.conf文件的樣子：

runners:
  hadoop:
    setup:
    - virtualenv venv
    - . venv/bin/activate
    - pip install nltk

我有一個使用nltk包的簡單工作。 我可以驗證此安裝腳本是否在工作程序節點上運行（我可以將簡單的命令（例如，將一些數據寫入/tmp的文件中，然后可以正常工作））。 但是，出現以下錯誤：

New python executable in venv/bin/python

是什么導致此錯誤？

Answer 1

感謝您將包部署到集群的想法。

至於您的問題，我認為它似乎沒有寫目錄的權限。
