title: Sqoop to write column names as headers
body: <p>I'm importing a table of data from Oracle into HDFS.
  I need to have Sqoop to write the column names as headers into the import files (files that end up in HDFS). Is there a way to do that? I basically need the import file to look like the following:</p>
  
  <p>ID, Country, City</p>
  
  <p>1,USA,Palo Alto</p>
  
  <p>2,Czech Republic,Brno</p>
  
  <p>3,USA,Sunnyvale</p>
  
  <p>instead of the following:</p>
  
  <p>1,USA,Palo Alto</p>
  
  <p>2,Czech Republic,Brno</p>
  
  <p>3,USA,Sunnyvale</p>
