### What changes were proposed in this pull request? This PR is a followup of https://github.com/apache/spark/pull/29703. It renames `HADOOP_VERSION` environment variable to `PYSPARK_HADOOP_VERSION` in case `HADOOP_VERSION` is already being used somewhere. Arguably `HADOOP_VERSION` is a pretty common name. I see here and there: - https://www.ibm.com/support/knowledgecenter/SSZUMP_7.2.1/install_grid_sym/understanding_advanced_edition.html - https://cwiki.apache.org/confluence/display/ARROW/HDFS+Filesystem+Support - http://crs4.github.io/pydoop/_pydoop1/installation.html ### Why are the changes needed? To avoid the environment variables is unexpectedly conflicted. ### Does this PR introduce _any_ user-facing change? It renames the environment variable but it's not released yet. ### How was this patch tested? Existing unittests will test. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
