> URL: https://issues.apache.org/jira/browse/SPARK-14147
> Project: Spark
> Issue Type: Bug
> Components: SparkR
> Reporter: Narine Kokhlikyan
>
> It seems that ML predictors in SparkR return an output which contains
> features represented by vector datatype, however SparkR doesn't support it
> and as a result features are being displayed as an environment variable.
> example:
> prediction <- predict(model, training)
> DataFrame[Sepal_Length:double, Sepal_Width:double, Petal_Length:double,
> Petal_Width:double, features:vector, prediction:int]
> collect(prediction)
> Sepal_Length Sepal_Width Petal_Length Petal_Width
> features prediction
