> Add checkInputColumn back to Params and print more info
> -------------------------------------------------------
>
> Key: SPARK-7137
> URL: https://issues.apache.org/jira/browse/SPARK-7137
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Affects Versions: 1.4.0
> Reporter: Joseph K. Bradley
> Priority: Trivial
>
> In the PR for [https://issues.apache.org/jira/browse/SPARK-5957],
> Params.checkInputColumn was moved to SchemaUtils and renamed to
> checkColumnType. The downside is that it no longer has access to the
> parameter info, so it cannot state which input column parameter was incorrect.
> We should keep checkColumnType but also add checkInputColumn back to Params.
> It should print out the parameter name and description. Internally, it may
> call checkColumnType.
