title: cannot overwrite hive scratchdir via ambari
body: <p>I changed the value of <code>hive.exec.scratchdir</code> to <code>/customdirname</code> via Ambari but the default folder <code>/tmp/hive</code> continues to be used, why?</p>
  
  <p>Is there a way to fix this so that hive only uses the modified directory?</p>
