Sean Owen commented on SPARK-13303:
-----------------------------------
Agree, I think this is one of those big "known issues", that Pyspark really
requires several dependencies to exist on all Python installations on the
cluster. I don't know if Spark itself can fix this. At least better errors
would be nice, but I'm also not sure how to fix that. Document it more
prominently?

> Key: SPARK-13303
> URL: https://issues.apache.org/jira/browse/SPARK-13303
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 1.6.0
> Environment: The python installation used by the driver (edge node)
> has pandas installed on it, while on the data nodes pandas do not have pandas
> installed in the python runtimes used. Pandas is never explicitly imported by
> pi.py.
> Reporter: Juliet Hougland
>
> Running `spark-submit pi.py` results in:
