Re: zeppelin R plot with exception

[Reminia Scarlet]

I’ve checked the jar zeppelin-spark_2.10-0.7.1.jar  on maven.

I decompiler the class ZeppelinRDisplay.class,  method htmlDisplay as below:

 private RDisplay htmlDisplay(Element body, String imageWidth)
  {
    ObjectRef div = ObjectRef.create(new String());
    
    JavaConversions..MODULE$.asScalaBuffer(body.children()).foreach(new 
AbstractFunction1()
    {
      public static final long serialVersionUID = 0L;
      
      public final void apply(Element element)
      {
        String eHtml = element.html();
        String eOuterHtml = element.outerHtml();
        
        eOuterHtml = eOuterHtml.replace("“%html 

It calls ObjectRef.create which method is from scala 2.11 not scala 2.10.

Anybody can tell why zepplin-spark_2.10 is not compiled base on scala 2.10?
