Software and Memory Requirements

Make sure that your system meets the following requirements:

Software Requirements

Ensure that the following software is installed on each host:

• Package managers:
  • RHEL/Rocky Linux:yum and rpm
  • Ubuntu:apt
• Utilities:scp, curl, unzip, tar, wget, and gcc
• OpenSSL: Version 1.0.1 (build 16 or later)
• Java: Java Development Kit (JDK) 17 or 21, including the corresponding development package (java-17-openjdk-devel or java-21-openjdk-devel).
• Python: Python 3.11 or 3.12, including the corresponding development package (python3.11-devel or python3.12-devel).

The selected Python version (3.11 or 3.12) must be configured as the default Python version when installing Ambari and the ODP cluster. Ensure that the python and python3 commands resolve to the selected version.
update-alternatives --config python
update-alternatives --config python3
python --version
python3 --version

Install the following required packages for ODP:

python3 -m pip install distro
python3 -m pip 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.

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

Package Size and Inode Count Requirements

Size and Inode values are approximate.
