>                 Key: SPARK-19453
>                 URL: https://issues.apache.org/jira/browse/SPARK-19453
>             Project: Spark
>          Issue Type: Improvement
>          Components: Documentation, PySpark, SQL
>    Affects Versions: 1.5.0, 1.6.0, 2.0.0, 2.1.0, 2.2.0
>            Reporter: Maciej Szymkiewicz
>
> Current docstring provides incorrect description of {{to_replace}} argument: 
> {quote}
>  If the value is a dict, then `value` is ignored and `to_replace` must be a mapping from column name (string) to replacement value.
> {quote}
> It looks like it has been copied from `na.fill` docs. In fact {{dict}} should provide mapping from value to replacement value. 
> Moreover docs fail to explain some fundamental limitations (like lack of support for heterogeneous values) and some usage scenarios.
