Re: Job failed when run R

[Eric Charles]

I don't have that issue - `%r 2+2` works out of the box.
The NoSuchMethodError is IMHO not related. The getElementsByTag should 
return a list. I would suscpect more the html() method which may not be 
present in previous JSoup versions.

Did you rebuild between those tests?

I used R interpreter. I have found the solution. I changed ".get(0)" 
to ".first()", then the exception is gone (see the following code 
snippet in ZeppelinRDisplay.scala:71).

private deftextDisplay(body: Element): RDisplay = {
   //RDisplay(body.getElementsByTag("p").get(0).html(), TEXT, SUCCESS)
   RDisplay(body.getElementsByTag("p").first().html(),TEXT,SUCCESS)
}

    What is your interpreter for this core? The R interpreter or Livy
