-------------------------------
Resolution: Done
> Incorrect fully qualified name for spark context
> ------------------------------------------------
>
> Key: TOREE-375
> URL: https://issues.apache.org/jira/browse/TOREE-375
> Project: TOREE
> Issue Type: Bug
> Environment: Jupyter Notebook with Toree latest master (1a9c11f5f1381c15b691a716acd0e1f0432a9a35) and Spark 2.0.2, Scala 2.11
> Reporter: Felix Schüler
> Priority: Critical
>
> When running below snippet in a cell I get a compile error for the MLContext Constructor. Somehow the fully qualified name of the SparkContext gets messed up.
> The same does not happen when I start a Spark shell with the --jars command and create the MLContext there.
> Snippet (the systemml jar is build with the latest master of SystemML):
> {code}
> %addjar file:///home/felix/repos/incubator-systemml/target/systemml-0.13.0-incubating-SNAPSHOT.jar -f
> import org.apache.sysml.api.mlcontext._
> import org.apache.sysml.api.mlcontext.ScriptFactory._
> val ml = new MLContext(sc)
> Starting download from file:///home/felix/repos/incubator-systemml/target/systemml-0.13.0-incubating-SNAPSHOT.jar
> Finished download of systemml-0.13.0-incubating-SNAPSHOT.jar
> Name: Compile Error
> Message: <console>:25: error: overloaded method constructor MLContext with alternatives:
> (x$1: org.apache.spark.api.java.JavaSparkContext)org.apache.sysml.api.mlcontext.MLContext <and>
> (x$1: org.apache.spark.org.apache.spark.org.apache.spark.org.apache.spark.org.apache.spark.SparkContext)org.apache.sysml.api.mlcontext.MLContext
> cannot be applied to (org.apache.spark.org.apache.spark.org.apache.spark.org.apache.spark.org.apache.spark.SparkContext)
> val ml = new MLContext(sc)
> ^
