System Requirements for POC Streams Cluster
Understand the hardware, operating system, database, and other requirements for the trial Cloudera Private Cloud Base software.
Hardware
- 32 GB RAM
- 100 GB disk space
Operating System
See the Cloudera Support Matrix for detailed information about supported operating systems.
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 passwordlesssudo
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.
