> Utility to convert python types to spark types compares Python "type" object
> rather than user's "tpe" for categorical data types
> --------------------------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-44142
> URL: https://issues.apache.org/jira/browse/SPARK-44142
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 3.4.0
> Reporter: Ted Chester Jenks
> Priority: Major
>
> In the typehints utility that converts python types to spark types, the line:
> {code:java}
> # categorical types
> elif isinstance(tpe, CategoricalDtype) or (isinstance(tpe, str) and type
> == "category"):
> return types.LongType() {code}
> uses Python's 'type' keyword in the comparison. Hence, it will always be
> false. Here, the user's type is actually stored in the variable 'tpe'.
