Configuring DNS

You must configure your instance or node to perform forward and reverse DNS lookups with your Cloudera Operational Database. Obtain the private IP address of your Cloudera environment and configure your instance to resolve hostnames from your Cloudera Operational Database. An instance must resolve the hostnames from your Cloudera Operational Database.

Each Cloudera environment acts as its own DNS nameserver. Obtain your environment's private IP address information and configure resov.conf on your instance to list your Cloudera environment's private IP address as a nameserver.

  1. Go to the Cloudera Management Console.
  2. Click Environments and select your environment from the list.
  3. Click Summary.
  4. Find the FreeIPA section and copy the contents of the Private IP field.
  5. Add the private IP address as a nameserver to the /etc/resolv.conf file in your instance. You can do this using the cat resolv.conf nameserver [***NAMESERVER IP ADDRESS***] command.
