title: Custom delimiter csv reader spark
body: <p>I would like to read in a file with the following structure with Apache Spark. </p>
  
  <pre><code>628344092\t20070220\t200702\t2007\t2007.1370
  </code></pre>
  
  <p>The delimiter is \t. How can I implement this while using spark.read.csv()?</p>
  
  <p>The csv is much too big to use pandas because it takes ages to read this file. Is there some way which works similar to </p>
  
  <pre><code>pandas.read_csv(file, sep = '\t')
  </code></pre>
  
  <p>Thanks a lot!</p>
