System Requirements for POC Streams Cluster

Understand the hardware, operating system, database, and other requirements for the trial CDP Private Cloud Base software.

Hardware

For each node in your cluster, allocate:

32 GB RAM
100 GB disk space

Operating System

Ensure you are using a Cloudera-supported operating system and version.

Table 1. Supported operating systems for 7.1.3
Operating System	Version (bold=new)
RHEL/CentOS/Oracle	7.6, 7.7, 7.8, 7.9
Ubuntu	18.04 Not supported for Cloudera Schema Registry
Debian	Not Supported

HTTP Proxy

The Cloudera Manager installer accesses archive.cloudera.com by using yum on RHEL systems. If your hosts access the Internet through an HTTP proxy, you can configure yum system-wide, to access archive.cloudera.com through a proxy.

To do so, modify the system configuration on the host node as follows:


OS	File	Property
RHEL-compatible	`/etc/yum.conf`	`proxy=http://server:port/`
Ubuntu	`/etc/apt/apt.conf`	`Acquire::http::Proxy "http://server:port";`

SELinux

If you are using SELinux in enforcing mode, you must disable SELinux for the Cloudera Manager installer to work.

Configure SELINUX=disabled in the /etc/selinux/config file.

Set:

setenforce 0

Cluster Host

The hosts you intend to use must satisfy the following requirements:

You must be able to log in to the Cloudera Manager Server host using the root user account or an account that has passwordless sudo privileges.
The Cloudera Manager Server host must have uniform SSH access on the same port to all hosts.
All hosts must have access to standard package repositories for the operating system and either archive.cloudera.com or a local repository with the required installation files.
