> Key: SPARK-39504
> URL: https://issues.apache.org/jira/browse/SPARK-39504
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core, SQL
> Affects Versions: 3.2.1
> Reporter: qian
> Priority: Major
>
> Since {{NullPointerException}} can possibly be thrown while calling the _equals_ method of {{{}Object{}}}, _equals_ should be invoked by a constant or an object that is definitely not {_}null{_}.
> {quote}Positive example: {{"test".equals(object);}}
> Counter example: {{object.equals("test");}}
