HyukjinKwon opened a new pull request #28243: [SPARK-29672][BUILD][PYTHON][FOLLOW-UP] Recover PySpark via pip installation with deprecated Python 2, 3.4 and 3.5 URL: https://github.com/apache/spark/pull/28243 ### What changes were proposed in this pull request? The RC fails to install against Python 2.7 via `pip`. We deprecated but didn't remove Python 2, 3.4 and 3.5 support yet. This PR partially reverts the changes from SPARK-29672 to recover Python 2, 3.4 and 3.5 pip installation. ```bash python2.7 -m pip install https://dist.apache.org/repos/dist/dev/spark/v3.0.0-rc1-bin/pyspark-3.0.0.tar.gz ``` ``` ...

To keep the deprecated support instead of removing. ### Does this PR introduce any user-facing change? No, it's the change in unreleased branches only yet. ### How was this patch tested? ```bash ./build/mvn -DskipTests -Phive -Phive-thriftserver clean package cd python python2.7 setup.py sdist python2.7 -m pip install pyspark-3.1.0.dev0.tar.gz ```
