body: <p>Removing extra quotes from each column values, following are my column values:</p>
  
  <pre><code>Array[Array[String]] = Array(Array("58, ""management"", ""married"", ""tertiary"", ""no"", 2143, ""yes"", ""no"", ""unknown"", 5, ""may"", 261, 1, -1, 0, ""unknown"", ""no"""), Array("4
  4, ""technician"", ""single"", ""secondary"", ""no"", 29, ""yes"", ""no"", ""unknown"", 5, ""may"", 151, 1, -1, 0, ""unknown"", ""no"""), Array("33, ""entrepreneur"", ""married"", ""secondary
  "", ""no"", 2, ""yes"", ""yes"", ""unknown"", 5, ""may"", 76, 1, -1, 0, ""unknown"", ""no"""))
  </code></pre>
  
  <p><strong>Expected output:</strong></p>
  
  <pre><code>Array[Array[String]] = Array(Array(58, management, married, tertiary, no, 2143, yes, no, unknown, 5, may, 261, 1, -1, 0, unknown, no), Array(44, technician, single, secondary, no, 29, yes, no, unknown, 5, may, 151, 1, -1, 0, unknown, no), Array(33, entrepreneur, married, secondary, no, 2, yes, yes, unknown, 5, may, 76, 1, -1, 0, unknown, no))
  </code></pre>
  
  <p>Following is the code:</p>
  
  <pre><code>val sqlContext = new org.apache.spark.sql.SQLContext(sc)
  import sqlContext.implicits._
  import org.apache.spark.sql._
  
  val data = sc.textFile("simplilearn/Project 1_dataset_bank-full.csv")
  val header = data.first()
  
  val data1 = data.filter(row=&gt;row != header)
  val finalSet = data1.map(row=&gt;row.split(";"))
  </code></pre>
  
  <p>The above RDD is stored in <code>finalSet</code> RDD.</p>
