Installing Python 3

Certain Cloudera services such as Cloudera Manager and Hue use Python 3.x. Installing Python 3.x is mandatory to deploy Cloudera Base on premises. Review the supported operating systems (OS) and use the corresponding instructions to install the recommended Python version.

Cloudera Manager 7.13.2 or higher versions does not work with Python 2.7. While using Cloudera Manager 7.13.2 or higher versions with Cloudera Runtime 7.3.1 or 7.1.9 version, you may remove all Python 2 versions from the operating system, only when the operating system allows you to remove the Python 2 version.

If you are running Cloudera Runtime 7.1.7 SP3 or below versions with Cloudera Manager 7.13.2, then Python 2.7 is still required for the Cloudera Runtime components. In this scenario, you must install both Python 2.7 (for Cloudera Runtime components) and Python 3.x (for Cloudera Manager 7.13.2).

Cloudera Manager 7.13.2 now supports only Python 3.11 version, when used in combination with Cloudera Runtime 7.3.2, 7.3.1.500 or higher versions, and 7.1.9 SP1 CHF11 or higher versions.

The tables in the following sections list the supported operating systems, the Python version that is distributed with those operating systems, and the Python 3.x versions required for deploying Cloudera:

Cloudera recommends you to install Python 3.11 before upgrading Cloudera Manager to 7.13.2 version to ensure smooth transition with minimal downtime. For information about migrating Python for various operating systems, see Python Guidelines.
Before upgrading to Cloudera Manager 7.13.2, you must install Python 3.11 on all hosts for RHEL 8, RHEL 9, Rocky Linux 9.4 or 9.6, Ubuntu 22.04, Ubuntu 24.04, Oracle 8.10 UEK, Oracle 9.2 UEK, SLES 15 SP5 and SLES 15 SP6.
Cloudera Manager now requires Python 3.11 on all versions of SLES 15, including SLES 15 SP5 and SLES 15 SP6. It is not possible to support two different versions of Python for the same major version of operating system. If the cluster was previously running Python 3.10, then you must upgrade to Python 3.11.
Due to a change in support from Python 3.10 to Python 3.11 for SLES 15 SP5 and SLES 15 SP6, only a regular upgrade of Cloudera Manager to 7.13.2 and Cloudera Runtime to 7.3.2 is possible and must occur sequentially without starting the cluster between the Cloudera Manager and Cloudera Runtime cluster upgrades.
Ubuntu 20 Operating System is not supported in Cloudera Manager 7.13.2 version.

Difference between standard and custom Python packages

The term standard Python package in Cloudera documentation refers to the Python package that is distributed with the OS, or an unmodified Python binary that is compiled from the source. If you have made modifications or customizations to the Python source code and then compiled the binaries into a package, then that is referred to as the custom Python package.
