holdenk commented on SPARK-21573:
---------------------------------
Yes we did drop 2.6 support. We should change the script to python2.7
explicitly and also, while we are thinking about it, probably consider throwing
an exception when PySpark is launched with Python 2.6 so its clear why its
failing.
> Tests failing with run-tests.py SyntaxError occasionally in Jenkins

> Key: SPARK-21573
> URL: https://issues.apache.org/jira/browse/SPARK-21573
> Project: Spark
> Issue Type: Test
> Components: Tests
> Affects Versions: 2.3.0
> Reporter: Hyukjin Kwon
> Priority: Minor
>
> It looks default {{python}} in the path at few places such as
> {{./dev/run-tests}} use Python 2.6 in Jenkins and it fails to execute
> {{run-tests.py}}:
> {code}
> python2.6 run-tests.py
> File "run-tests.py", line 124
> {m: set(m.dependencies).intersection(modules_to_test) for m in
> modules_to_test}, sort=True)
> ^
> SyntaxError: invalid syntax
> {code}
> It looks there are quite some places to fix to support Python 2.6 in
> {{run-tests.py}} and related Python scripts.
> We might just try to set Python 2.7 in few other scripts running this if
> available.
