> MLlib GeneralizedLinearRegression family and link should case insensitive
> --------------------------------------------------------------------------
>
> Key: SPARK-19155
> URL: https://issues.apache.org/jira/browse/SPARK-19155
> Project: Spark
> Issue Type: Bug
> Components: ML
> Reporter: Yanbo Liang
> Assignee: Yanbo Liang
> Fix For: 2.0.3, 2.1.1, 2.2.0
>
>
> ML {{GeneralizedLinearRegression}} only support lowercase input for
> {{family}} and {{link}} currently. For example, the following code will throw
> exception:
> {code}
> val trainer = new GeneralizedLinearRegression().setFamily("Gamma")
> {code}
> However, R glm only accepts families: {{gaussian, binomial, poisson, Gamma}}.
> We should make {{family}} and {{link}} case insensitive.
