Subject [jira] [Created] (SPARK-23460) PySpark concurrency python egg cache directory
Date Sun, 18 Feb 2018 06:25:00 GMT
Dmitiry created SPARK-23460:
-------------------------------

             Summary: PySpark concurrency python egg cache directory
                 Key: SPARK-23460
                 URL: https://issues.apache.org/jira/browse/SPARK-23460
             Project: Spark
          Issue Type: Question
          Components: PySpark
    Affects Versions: 2.1.2
         Environment: YARN last
            Reporter: Dmitiry


We are experiencing intermittent failures when running task on pyspark while installing dependencies
through --py-files with python egg. We set (else permission denied on egg cache):
{noformat}
--conf "spark.executorEnv.PYTHON_EGG_CACHE=./.python-eggs"{noformat}
 

Error:
{noformat}
INFO - File "build/bdist.linux-x86_64/egg/ua_parser/user_agent_parser.py", line 409, in <module>

INFO - The following error occurred while trying to extract file(s) to the Python egg
INFO - cache:

INFO - [Errno 17] File exists: './.python-eggs'
INFO - 
INFO - The Python egg cache directory is currently set to:
INFO - 
INFO - ./.python-eggs/
INFO - 
INFO - Perhaps your account does not have write access to this directory? You can
INFO - change the cache directory by setting the PYTHON_EGG_CACHE environment
INFO - variable to point to an accessible directory.{noformat}
 

We create a package with an option `safe_zip=False`. But pyspark whatever use egg cache directory.

Is there any way around this?
