[jira] [Commented] (SPARK-18644) spark-submit fails to run python scripts with specific names

Marcelo Vanzin commented on SPARK-18644:
----------------------------------------

I wonder if this is just a python issue. python has a module named {{tokenize}}, and if you name your script {{tokenize.py}}, you're masking that module, so anything that depends on it directly or indirectly will stop working.

>          Issue Type: Bug
>          Components: PySpark, Spark Submit
>    Affects Versions: 2.0.2

> I'm trying to run simple python script named tokenize.py with spark-submit. The script only imports SparkContext:
> from pyspark import SparkContext
> And I run it with:
> spark-submit --packages org.apache.spark:spark-streaming-kafka-0-8_2.11:2.0.2 tokenize.py
> However, the script fails:
> ImportError: cannot import name SparkContext
> I have set all necessary environment variables, etc. Strangely, it seems the filename is causing this error. If I rename the file to, e.g., tokenizer.py and run again, it runs fine.
