> Python Lint does not actually check for `black` formatter
> ---------------------------------------------------------
>
> Key: SPARK-39881
> URL: https://issues.apache.org/jira/browse/SPARK-39881
> Project: Spark
> Issue Type: Improvement
> Components: Build, PySpark
> Affects Versions: 3.3.0
> Reporter: Martin Grund
> Priority: Major
>
> In our current `dev/lint-python` script we execute the following check: {{}}
>
> {code:java}
> $BLACK_BUILD 2> /dev/null
> if [ $? -ne 0 ]; then
> # ...
> fi{code}
> However, even if black is installed simply invoking it will actually return a
> non-zero exit code because no src files have been specified. To correctly
> check for the existence of `black` we need a different check.
