title: How to automatically get the current date and time in a column using HIVE
body: <p>Hey I have two columns in my HIVE table :</p>
  
  <p>For example :- </p>
  
  <pre><code>c1 : name
  c2 : age
  </code></pre>
  
  <p>Now while creating a table I want to declare two more columns which automatically give me the current date and time when the row is loaded.
   eg:  <code>John  24  26/08/2015 11:15</code>
  How can this be done?</p>
