title: Cloudera/Hive - Can't access tables after hostname change
body: <p>I created a Cloudera cluster and imported some sample test files from oracle DB. But after a while I had to change the hostnames of the nodes. I followed the guide mentioned in cloudera site and everything worked fine. But when I try to access tables(using both hive and impala) I created earlier I get the following error:
  Fetching results ran into the following error(s):</p>
  
  <p>java.io.IOException: java.lang.IllegalArgumentException: java.net.UnknownHostException: [Old Host Name]</p>
  
  <p>Then I created another table under the same DB (Using Hue>Metastore Tables) and I can access these new tables created under the new hostname with no issue.</p>
  
  <p>Can someone explain how I can access my old tables without reverting back my hostnames. Can I access metastore db and change the table pointers to new hostname.</p>
