title: output hive results in parquet format files
body: <p>Can you export a hive query result into parquet file formats? I can export results as a tsv like this:</p>
  
  <pre><code>INSERT OVERWRITE DIRECTORY '/home/user/events'
  row format delimited 
  fields terminated by '\t'
  </code></pre>
  
  <p>but how do I tell it to do it in parquet format?</p>
