title: How to save CSV with all fields quoted?
body: <p>The below code does not add the double quotes which is the default. I also tried adding # and single quote using option <code>quote</code> with no success. I also used <code>quoteMode</code> with <code>ALL</code> and <code>NON_NUMERIC</code> options, still no change in the output.</p>
  
  <pre><code>s2d.coalesce(64).write
    .format("com.databricks.spark.csv")
    .option("header", "false")
    .save(fname)
  </code></pre>
  
  <p>Are there any other options I can try? I am using spark-csv 2.11 over spark 2.1.</p>
  
  <p>Output it produces:</p>
  
  <pre><code>d4c354ef,2017-03-14 16:31:33,2017-03-14 16:31:46,104617772177,340618697
  </code></pre>
  
  <p>Output I am looking for:</p>
  
  <pre><code>“d4c354ef”,”2017-03-14 16:31:33”,”2017-03-14 16:31:46”,104617772177,340618697  
  </code></pre>
