System Requirements for POC Streams Cluster

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


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.

Operating System Supported Version
RHEL/CentOS/Oracle 7.6, 7.7
Oracle Linux (OL)
  • 7.6, 7.4, 7.3, 7.2 (UEK default)
  • 6.10 (UEK default)
  • 18.04 LTS (Bionic)
  • 16.04 LTS (Xenial)

HTTP Proxy

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


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.


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 or a local repository with the required installation files.
