> -----------------------------------------------------
>
> Key: SPARK-6290
> URL: https://issues.apache.org/jira/browse/SPARK-6290
> Project: Spark
> Issue Type: Bug
> Components: ML
> Affects Versions: 1.3.0
> Reporter: Joseph K. Bradley
> Assignee: Xiangrui Meng
> Priority: Minor
> Fix For: 1.4.0
>
>
> In checkInputColumn, if data types do not match, it tries to print an error
> message with this in it:
> {code}
> Column param description: ${getParam(colName)}"
> {code}
> However, getParam cannot be called on the string colName; it needs the
> parameter name, which this method is not given. This causes a weird error
> which users may find hard to understand.
