Helps you decide if an OS upgrade is needed when you are using the Installer to upgrade
to core 6.2.0.
OS Versions Supported by Core 6.2.0
Most upgrades to core 6.2.0 require upgrading the cluster operating system. You can run
core 6.2.0 with the following Linux operating systems:
- Red Hat
Enterprise Linux / CentOS 8.2, and 8.3
- Ubuntu 18.04
- Ubuntu 16.04
- Oracle Enterprise
Linux 8.2
For the latest OS support information, see Operating System Support Matrix (Release 6.x).
OS Upgrade Not Required
If the Linux OS for your cluster is supported for core 6.2.0, you do NOT need to upgrade
the OS before you upgrade core. For example, if your cluster runs core 6.1.0 on Ubuntu 18.04
and you want to upgrade to core 6.2.0 on 18.04, you can perform the upgrade entirely through
the Installer by using the Version Upgrade feature. See Upgrading Core With the Installer.
OS Upgrade Required
If the Linux OS for your cluster is not supported for core 6.2.0 (not included in the list
earlier on this page), you must upgrade the Linux OS before upgrading to core 6.2.0. Use the
following steps. After upgrading the OS, you can use the Installer to complete the upgrade
to core 6.2.0:
- Make sure you are using the latest version of the Installer, which is required for
core 6.2.0. For more information, see Selecting an Installer Version to Use.
- Apply the latest core patch on all nodes of the cluster to be upgraded.
- Shut down the cluster as described in one of these topics:
- Shut down the Installer (requires
root
authentication):systemctl stop mapr-installer
- Upgrade the OS to one of the supported versions mentioned earlier on this page. For
upgrade information, see Upgrading Your Red Hat, CentOS, or Ubuntu Operating System.
- Check the Installer status to see if it is
started:
systemctl status mapr-installer
- If the Installer isn't started, start it (requires
root
authentication):systemctl start mapr-installer
- Continue with the upgrade workflow using the Installer. See Upgrading Core With the Installer.
