[jira] [Updated] (SPARK-13982) SparkR - KMeans predict: Output
column name of features is an unclear, automaticly genetared text
[ https://issues.apache.org/jira/browse/SPARK-13982?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Narine Kokhlikyan updated SPARK-13982:
--------------------------------------
Summary: SparkR - KMeans predict: Output column name of features is an unclear, automaticly genetared text (was: SparkR - KMeans predict: Output column name of features is an unclear, automatic genetared text)
> SparkR - KMeans predict: Output column name of features is an unclear, automaticly genetared text
> -------------------------------------------------------------------------------------------------
>
> Key: SPARK-13982
> URL: https://issues.apache.org/jira/browse/SPARK-13982
> Project: Spark
> Issue Type: Bug
> Reporter: Narine Kokhlikyan
> Priority: Minor
>
> Currently KMean-predict's features' output column name is set to something like this: "vecAssembler_522ba59ea239__output", which is the default output column name of the "VectorAssembler".
> Example:
> showDF(predict(model, training)) shows something like this:
> DataFrame[Sepal_Length:double, Sepal_Width:double, Petal_Length:double, Petal_Width:double, **vecAssembler_522ba59ea239__output:**vector, prediction:int]
> This name is automatically generated and very unclear from user perspective.
