  <p>I tried to change the permission of db-data folder to 700 and also dropped the SCHEMA_VERSION table as per this <a href="http://community.cloudera.com/t5/Cloudera-Manager-Installation/Can-t-start-Cloudera-Manager-or-Hadoop-Services-after-hard/td-p/14380" rel="nofollow">link</a>  but no luck</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>In DB logs from /var/log/cloudera-scm-server/db.log i got following FATAL error:</p>
  
  <pre><code>FATAL:  no pg_hba.conf entry for host "192.168.6.109", user "scm", database "scm", SSL off
