--------------------------------------

> ---------------------------------------------------------
>
> Key: SPARK-7651
> URL: https://issues.apache.org/jira/browse/SPARK-7651
> Project: Spark
> Issue Type: Bug
> Components: MLlib, PySpark
> Affects Versions: 1.3.0, 1.3.1, 1.4.0
> Reporter: Joseph K. Bradley
> Priority: Minor
>
> In PySpark, GaussianMixtureModel predict and predictSoft test if the argument
> is an RDD and operate correctly if so. But if the argument is not an RDD,
> they fail silently, returning nothing.
