Narine Kokhlikyan updated SPARK-14147: -------------------------------------- Description: It seems that ML predictors in SparkR return an output which contains features represented with 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 1 5.1 3.5 1.4 0.2 <environment: 0x10b7a8870> 1 2 4.9 3.0 1.4 0.2 <environment: 0x10b79d498> 1 3 4.7 3.2 1.3 0.2 <environment: 0x10b7960a8> 1 was: It seems that ML predictors in SparkR return an output which contains features represented with 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) collect(prediction) Sepal_Length Sepal_Width Petal_Length Petal_Width features prediction 1 5.1 3.5 1.4 0.2 <environment: 0x10b7a8870> 1 2 4.9 3.0 1.4 0.2 <environment: 0x10b79d498> 1 3 4.7 3.2 1.3 0.2 <environment: 0x10b7960a8> 1 > SparkR - ML predictors return features with vector datatype, however SparkR > doesn't support it > ---------------------------------------------------------------------------------------------- > > Key: SPARK-14147 > URL: https://issues.apache.org/jira/browse/SPARK-14147 > Project: Spark > Issue Type: Bug > Reporter: Narine Kokhlikyan > > It seems that ML predictors in SparkR return an output which contains > features represented with 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 > 1 5.1 3.5 1.4 0.2 <environment: > 0x10b7a8870> 1 > 2 4.9 3.0 1.4 0.2 <environment: > 0x10b79d498> 1 > 3 4.7 3.2 1.3 0.2 <environment: > 0x10b7960a8> 1 -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
