title: SparkUI cannot be reached while debugging in IntelliJ
body: <p>I am a newbie in Spark programming and developing a Spark application using IntelliJ IDE. What I want to achieve is reaching Spark Web UI while continuing debugging in IntelliJ. However, I'am getting "This site can't be reached" error when trying to reach the URL provided by SparkContext. </p>

  <p>Is it possible to both monitoring the Spark Web UI and debugging in IntelliJ?</p>
  
  <p>Thanks in advance.</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>I've already tried <a href="http://localhost:4040" rel="noreferrer">http://localhost:4040</a> and <a href="http://localhost:8088" rel="noreferrer">http://localhost:8088</a>. Also, I could reach Spark Web UI from <a href="http://localhost:4040" rel="noreferrer">http://localhost:4040</a> when starting spark-shell via command line interface.</p>
