Re: zeppelin R plot with exception
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?
