Hello! ;) I'm new to spark development and have been trying to set up my dev environment for hours without much success. :-(
Firstly, I'm wondering why my ./dev/run-tests fails even though in on the master branch. This is the error: flake8 checks failed: ./examples/src/main/python/sql/arrow.py:67:16: E999 SyntaxError: invalid syntax def func(s1: pd.Series, s2: pd.Series, s3: pd.DataFrame) -> pd.DataFrame: ^ ./python/run-tests.py:123:48: E999 SyntaxError: invalid syntax print(decoded_line, end='') ^ ./dev/run-tests-jenkins.py:43:20: E999 SyntaxError: invalid syntax print(msg, file=sys.stderr) ^ ./dev/run-tests.py:273:44: E999 SyntaxError: invalid syntax print(line.decode('utf-8'), end='') ^ ./dev/pip-sanity-check.py:31:76: E999 SyntaxError: invalid syntax print("Value {0} did not match expected value.".format(value), file=sys.stderr) ^ 5 E999 SyntaxError: invalid syntax 5 1 [error] running /home/vagrant/gtSync/suddhuApache/spark/dev/lint-python ; received return code 1 Would love to have some help with setting up my dev environment. I've done some other open source contributions and setting up the dev env there was easier... Regards Sudha ᐧ
