Shane Knapp updated SPARK-29672:
--------------------------------
    Description: 
python 2.7 is EOL jan 1st 2020: [https://github.com/python/devguide/pull/344]

it's time, at least for 3.0+ to remove python 2.7 test support and migrate the 
test execution framework to python 3.6.

this PR ([https://github.com/apache/spark/pull/26330]) does all of the above.

two things of note:

1) there are a bunch of other python scripts in the repo that need to be 
updated to '/usr/bin/env python3': 
{noformat}
$ grep -r "env python" * |grep -v python3
dev/create-release/releaseutils.py:#!/usr/bin/env python
dev/create-release/generate-contributors.py:#!/usr/bin/env python
dev/create-release/translate-contributors.py:#!/usr/bin/env python
dev/github_jira_sync.py:#!/usr/bin/env python
dev/merge_spark_pr.py:#!/usr/bin/env python
python/pyspark/version.py:#!/usr/bin/env python
python/pyspark/find_spark_home.py:#!/usr/bin/env python
python/setup.py:#!/usr/bin/env python{noformat}
2) there are 135 python files in the spark repo that need to have `from 
__future__ import print_function` removed (see attached file 
'print_function_list.txt')

> remove python2 tests and test infra
