title: How to setup Cloudera Hadoop to run on Ubuntu localhost?
body: <p>I am trying to run all Hadoop servers on a single Ubuntu localhost. All ports are open and my /etc/hosts file is</p>
  
  <pre><code>127.0.0.1   frigate frigate.domain.local    localhost
  # The following lines are desirable for IPv6 capable hosts
  ::1     ip6-localhost ip6-loopback
  fe00::0 ip6-localnet
  ff00::0 ip6-mcastprefix
  ff02::1 ip6-allnodes
  ff02::2 ip6-allrouters
  </code></pre>
  
  <p><strong>When trying to install cluster  Cloudera manager fails with the following messages:</strong></p>
  
  <pre><code>Installation failed. Failed to receive heartbeat from agent.
  
  Ensure that the host's hostname is configured properly.
  Ensure that port 7182 is accessible on the Cloudera Manager server (check firewall rules).
  Ensure that ports 9000 and 9001 are free on the host being added.
  Check agent logs in /var/log/cloudera-scm-agent/ on the host being added (some of the logs can be found in the installation details).

  <p>I run my Ubuntu-12.04 node from home connected by Wifi/dialup modem to my provider. What configuration is missing?</p>
