python - spark-submit python 文件 ‘home/.python-eggs’ 权限被拒绝

Question

我在使用 spark-submit 运行 python 文件时遇到了问题。当 'map' 代码在 'executor' 中运行时，问题如下:

Traceback (most recent call last):

  pkg_resources.ExtractionError: Can't extract file(s) to egg cache
  The following error occurred while trying to extract file(s) to the Python egg
  cache:
    [Errno 13] Permission denied: '/home/.python-eggs' 
  The Python egg cache directory is currently set to:  
   /home/.python-eggs  
 Perhaps your account does not have write access to this directory?  You can
 change the cache directory by setting the PYTHON_EGG_CACHE environment
 variable to point to an accessible directory.

我给每个executor都设置了PYTHON_EGG_CACHE环境变量，并且在我的程序中也写了'os.environ['PYTHON_EGG_CACHE'] = "/tmp/"'，但是问题依旧。

我的代码:

import os,sys
print "env::::"+os.environ['PYTHON_EGG_CACHE']
from pyspark import SparkConf, SparkContext
# Load and parse the data
def parsePoint(line):
    import os
    print "env::::"+os.environ['PYTHON_EGG_CACHE']
    os.environ['PYTHON_EGG_CACHE'] = "/tmp/"
    values = [float(x) for x in line.split(' ')]
    return line

if __name__ == "__main__":
    os.environ['PYTHON_EGG_CACHE'] = "/tmp/"
    print "env::::"+os.environ['PYTHON_EGG_CACHE']
    conf = SparkConf()
    sc = SparkContext(conf = conf)
    data = sc.textFile(sys.argv[1])
    parsedData = data.map(parsePoint)
    parsedData.collect()

我在“独立”模式下运行此 python 程序并成功。这是我的提交命令:

spark-submit --name test_py --master yarn-client testpy.py input/sample_svm_data.txt

是 yarn 的问题吗？

这已经晚了，但这是我在 google 上发现的第一个结果...之前的答案很有帮助(我想知道我必须修改哪些环境变量)，但请不要修改编辑 Spark 源，只是使用适当的工具更改环境变量，将其添加到您的 spark.conf 变量中...

spark.executorEnv.PYTHON_EGG_CACHE="./.python-eggs/"
spark.executorEnv.PYTHON_EGG_DIR="./.python-eggs/"
spark.driverEnv.PYTHON_EGG_CACHE="./.python-eggs/"
spark.driverEnv.PYTHON_EGG_DIR="./.python-eggs/"

(我不想使用/tmp/因为 . 会在我的工作结束后被删除，所以 eggs 也应该消失 IMO)
