> Random Forest Predict Execution Fails
> -------------------------------------
>
> Key: SYSTEMML-638
> URL: https://issues.apache.org/jira/browse/SYSTEMML-638
> Project: SystemML
> Issue Type: Bug
> Affects Versions: SystemML 0.10
> Reporter: Stacey Ronaghan
>
> Issue executing the prediction for random forest algorithm on SystemML 0.10
> (incubating) via MLContext with Scala Spark on a cluster.
> Related to [SYSTEMML-597|https://issues.apache.org/jira/browse/SYSTEMML-597].
> X is the same input passed into execute for random-forest.dml (mentioned in
> [SYSTEMML-597|https://issues.apache.org/jira/browse/SYSTEMML-597]) and M is
> its output model.
> Code:
> {code}
> // Register inputs & outputs for prediction
> ml.reset()
> ml.registerInput("X", X)
> //ml.registerInput("Y", Y)
> ml.registerInput("M", M)
> ml.registerOutput("P")
> //ml.registerOutput("A")
> // Run the script
> //val nargs = Map("X" -> "", "Y" -> "", "M" -> "", "P" -> "", "A" -> "")
> val nargs = Map("X" -> "", "M" -> "", "P" -> "")
> val outputs =
> ml.execute("/home/biadmin/spark-enablement/installs/SystemML/algorithms/random-forest-predict.dml",
> nargs)
> val P = outputs.getDF(sqlContext, "P")
> //val A = outputs.getDF(sqlContext, "A")
> {code}
> Output:
> {code}
