Apache Spark reassigned SPARK-12268:
------------------------------------
Assignee: Apache Spark
> pyspark shell uses execfile which breaks python3 compatibility
> --------------------------------------------------------------
>
> Key: SPARK-12268
> URL: https://issues.apache.org/jira/browse/SPARK-12268
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 1.5.2, 1.6.1
> Reporter: Erik Selin
> Assignee: Apache Spark
>
> The pyspark shell allows custom start scripts to run using the PYTHONSTARTUP
> environment variable. The value specified there will get run at the end of
> the shell startup by a call to execfile. However, execfile is deprecated in
> python3 and thus this does not work for python3 users. The simply fix is to
> follow the 2to3 recommendation and read, compile and exec the file manually
> as per this PR: https://github.com/apache/spark/pull/10255
