title: Exception when starting Hive in Ambari in HDP 2.6
body: <p>Error message: <code>Caught an exception while executing custom service command: &lt;type 'exceptions.OSError'&gt;: [Errno 13] Permission denied: '/var/lib/ambari-agent/cred/conf/hive/hive-site.jceks'; [Errno 13] Permission denied: '/var/lib/ambari-agent/cred/conf/hive/hive-site.jceks'</code></p>
  
  <p>The file exists and setting it to 777 does not solve the problem.</p>
  
  <p>The service that fails to start is "MySQL Server". I can start and restart the msqld on the commandline.    </p>
