title: Importing jSON Array into Hive/Hadoop
body: <p>I'm using the <a href="http://hortonworks.com/products/hortonworks-sandbox/#tutorial_gallery" rel="nofollow">HortonWorks Hadoop Sandbox</a> and I have imported a jSON string into a table, as per <a href="http://pkghosh.wordpress.com/2012/05/06/hive-plays-well-with-json/" rel="nofollow">this guide</a> however I run into trouble as my string contains an array which is not handled well by json_tuple(). I have tried the expolode() function, but that returns the following error:</p>
  
  <p>"Error occurred executing hive query: OK FAILED: UDFArgumentException explode() takes an array or a map as a parameter"</p>
  
  <p>What does that mean exactly and how can I fix it? Would the problem be with the format of the table? I just followed as per the guide above and created the table with:</p>
  
  <pre><code>CREATE EXTERNAL TABLE games
  (
      value STRING
  )
  LOCATION '/user/hue/games'
  </code></pre>
  
  <p>The value I am trying to explode is an array like this:</p>
