-----------------------------------------
Note: to build project, needed to have Map be <String, ?>. Build fixed by

> Remove Script in() method Scala Map types
> -----------------------------------------
>
> Key: SYSTEMML-884
> URL: https://issues.apache.org/jira/browse/SYSTEMML-884
> Project: SystemML
> Issue Type: Bug
> Components: APIs
> Reporter: Deron Eriksson
> Assignee: Deron Eriksson
> Fix For: SystemML 0.11
>
>
> The following MLContext code from Spark Shell:
> {code}
> val addScript = dml("print(a + b)")
> addScript.in(Map("a"->1,"b"->2))
> {code}
> gives:
> {code}
> <console>:34: error: overloaded method value in with alternatives:
> (x$1: Seq[Object])org.apache.sysml.api.mlcontext.Script <and>
> (x$1:
> scala.collection.Map[String,Object])org.apache.sysml.api.mlcontext.Script
> <and>
> (x$1: java.util.Map[String,Object])org.apache.sysml.api.mlcontext.Script
> cannot be applied to (scala.collection.immutable.Map[String,Int])
> addScript.in(Map("a"->1,"b"->2))
> {code}
> An annoying fix from Scala would be:
> {code}
> addScript.in(Map("a"->1.asInstanceOf[AnyRef],"b"->2.asInstanceOf[AnyRef]))
> {code}
> This is not good from a usability standpoint.
> An alternative that has good usability is to remove the <String, Object>
> types from the scala.collection.Map of the in()/input() methods.
