6. Prepare the Environment

To deploy your HDP instance, you need to prepare your deploy environment:

 6.1. Enable NTP on the Cluster

The clocks of all the nodes in your cluster must be able to synchronize with each other. If your system does not have access to the Internet, set up a master node as an NTP server.

 6.2. Check DNS

All hosts in your system must be configured for DNS and Reverse DNS.


If you are unable to configure DNS and Reverse DNS, you must edit the hosts file on every host in your cluster to contain each of your hosts.

 6.3. Disable SELinux

SELinux can interfere with the installation process.
