title: hive.cli.print.header=true not working
body: <p>I'm trying to export the results of a query to the file system.  Everything works fine, except that I can't get the column headers as part of the file.
  Here's what my script looks like:</p>
  
  <pre><code>set hive.cli.print.header=true;
  set mapreduce.task.timeout=0;
  set hive.auto.convert.join=false;
  set hive.execution.engine=tez;
  
  insert overwrite local directory '/work/output'
  ROW FORMAT DELIMTED
  FIELDS TERMINATED BY '|'
  
  select...
  </code></pre>
  
  <p>Am I missing something?</p>
