title: Spark-Csv Write quotemode not working
body: <p>I am trying to write a DataFrame as a CSV file using Spark-CSV (<a href="https://github.com/databricks/spark-csv" rel="noreferrer">https://github.com/databricks/spark-csv</a>)</p>
  
  <p>I am using the command below</p>
  
  <pre><code>res1.write.option("quoteMode", "NONE").format("com.databricks.spark.csv").save("File")
  </code></pre>
  
  <p>But my CSV file is always written as</p>
  
  <p>"London"<br>
  "Copenhagen"<br>
  "Moscow"</p>
  
  <p>instead of</p>
  
  <p>London<br>
  Copenhagen<br>
  Moscow  </p>
