After upgrading core, several manual steps are
required.
Considerations for Upgrades Using the Installer
If you use the Installer to upgrade the cluster, some post-upgrade steps for core do not need to be performed. This page describes the post-upgrade steps that are performed by the Installer and the steps that you must perform manually.
Step 1: Restart and Check Cluster Services
After upgrading core using either a manual offline or rolling upgrade method (not upgrading with the Installer) and upgrading your ecosystem components, configure and restart the cluster and services.
Step 3: Upgrade Clients
After you upgrade your cluster, you may also need to upgrade your data-fabric client or POSIX client.
Step 4: Enable New Features
Describes the new features to enable after upgrading core without the Installer using a manual offline or rolling upgrade method.
Step 5: Update Hadoop Configuration File
When manually upgrading (manual offline and manual rolling upgrade) from version 4.x to version 6.x and switching from classic mode to YARN mode, you must manually update the Hadoop configuration file.
