General requirements for DataPlane installation

Understanding the requirements and recommendations indicated below can help to avoid common issues during and after DataPlane installation.

• Be sure to review the DP Platform Support Matrix to confirm you meet the environment and system requirements, including Docker and networking.
• You need to have root access to the nodes on which all DP services will be installed.
• Every host name used with DataPlane must be resolvable by DNS or configured in the /etc/hosts file on the DataPlane container, so that host names can be resolved between all cluster nodes.

  Using a DNS server is the recommended method, but if the instances are added to /etc/hosts, you must explicitly register the cluster host names within the DataPlane Docker containers. It is not sufficient to have the host names included in the /etc/hosts file on the DP Platform host. See the DP Platform Administration guide for instructions.

• DataPlane supports only PEM-encoded certificates and only with OpenSSL 1.0.2k or later.
• If you are using AWS, do not use the public DNS to access DataPlane.

  Use a public IP address or set up and use a DNS (Route 53) fully qualified domain name (FQDN).

• Have your enterprise LDAP details available.

  See Enterprise LDAP Requirements for more details.

• Determine which DP Apps you plan to install and which cluster(s) you plan to add to DataPlane.

  Be sure to review the app-specific documentation thoroughly to make sure you can meet the app-specific requirements. For example, depending on your choice of apps, your cluster requirements might change. This includes (but is not limited to) a minimal HDP or HDF version, setup and configuration of Knox, and other cluster requirements. See Preparing Your Cluster for more details.
