2. Software and Memory Requirements

Make sure that your system meets the following requirements:

Software Requirements

On each of your hosts:

• yum and rpm (RHEL/Rocky Linux)
• apt (Ubuntu)
• scp, curl, unzip, tar, wget, and gcc
• OpenSSL (v1.01, build 16 or later)
• Java11 with devel package
• Python 3.11 (with python-devel)

Python 3.11.x must be the default Python version when installing Ambari and the ODP cluster.

update-alternatives --config python

update-alternatives --config python3

Install the following required packages for ODP:

pip3.11 install distro

pip3.11 install lxml

update-alternatives --config python

Memory Requirements

The Ambari host must have at least 1 GB RAM, with 500 MB free.

To check the available memory on any host, run the free -m command.

Note Use these values as guidelines. Make sure to test them for your specific environment.

Package Size and Inode Count Requirements

Note Size and Inode values are approximate.
