title: spark read from hdfs with kerberos and write on local filesystem
body: <p>I am trying to get the following use case:</p>
  
  <ol>
  <li>spark read files from HDFS with Kerberos in parquet format</li>
  <li>spark write this files in csv format</li>
  </ol>
  
  <p>If I write to hdfs, it works perfectly. If I try to write to local filesystem, it doesn´t work: <code>"main" java.io.IOException: Can't get Master Kerberos principal for use as renewer</code></p>
  
  <p>I am using Spark 1.6.2.</p>
  
  <p>To sumarize, my code is</p>
  
  <pre><code>val dfIn = sqc.read.parquet(pathIsilon)
  dfIn.coalesce(1).write.format("com.databricks.spark.csv").save(pathFilesystem)
  </code></pre>
