> -If python3-venv is not installed on Ubuntu systems, the "python3 -m venv" command will fail. bin/cmake_aux/create_py3_virtualenv.sh was intended to handle that and fall back to the impala-virtualenv command. That is working. Instead, it fails with this message:

> shutil.SameFileError: '/usr/bin/python3' and '/home/ubuntu/Impala/shell/build/py3_venv/bin/python3' are the same file{noformat}
> This is because the failed "python3 -m venv" command left behind a directory, and the virtualenv command can't handle it. bin/cmake_aux/create_py3_virtualenv.sh should remove the directory before falling back to impala-virtualenv.
