title: Hive "Creating Hive Metastore Database Tables" command fails on installation 'Path A' using Cloudera Manager
body: <p>I am installing Cloudera Manager onto an ec2 instance. I only added a single other ec2 instance to the cluster. 
  The installation succeeded, but when the manager initiates the cluster services (step 9 of 21) I get the 
  following error:  </p>
  
  <pre><code>[2013-07-12 18:44:35,906]ERROR 63227[main]
  com.cloudera.enterprise.dbutil.SqlRunner.open(SqlRunner.java:111)
  
  - Error connecting to db with user 'hive' and jdbcUrl 'jdbc:postgresql://ip-xx-xxx-
  xx-x.ec2.internal:7432/hive'
  </code></pre>
  
  <p>I manually opened port 7432 on the ec2 instance created by cloudera, because it did not appear to be open, I'm not sure if that was a bad idea. The cloudera manager docs claim
  that the postgres db will be auto created on installation so I don't think that is the 
  problem either.</p>
