  <p>I am trying to replace all special character after reading file into RDD, </p>
  
  <pre><code>    val fileReadRdd = sc.textFile(fileInput)
      val fileReadRdd2 = fileReadRdd.map(x =&gt; x.map(_.replace(","," ")))
      val fileFlat = fileReadRdd.flatMap(rec =&gt; rec.split(" "))
  </code></pre>
  
  <p>I am getting following error </p>
  
  <pre><code>Error:(41, 57) value replace is not a member of Char
      val fileReadRdd2 = fileReadRdd.map(x =&gt; x.map(_.replace(",","")))
  </code></pre>
