title: What is the best way to check existence of Hive table?
body: <p>Options in my mind:</p>
  
  <ol>
  <li><p>Fire <code>DESCRIBE TABLE;</code></p></li>
  <li><p>Fire <code>SELECT 1 FROM TABLE;</code></p></li>
  </ol>
  
  <p>These queries will fail if table does not exist.</p>
  
  <p>Which is better way? Or is there any other good approach?</p>
