Apache Spark reassigned SPARK-39881:
------------------------------------

    Assignee:     (was: Apache Spark)

> 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.
