title: how to replace characters in hive?
body: <p>I have a string column <code>description</code> in a hive table which may contain tab characters <code>'\t'</code>, these characters are however messing some views when connecting hive to an external application.
  is there a simple way to get rid of all tab characters in that column?. I could run a simple python program to do it, but I want to find a better solution for this.</p>
