Workflow: Manual Rolling Upgrade to MapR 6.1

This page summarizes the steps for upgrading from MapR 5.2.x to MapR 6.1 by using a manual rolling upgrade. In this workflow, the cluster to be upgraded is nonsecure; after the upgrade, the cluster will continue to be nonsecure, but can be secured by using manual steps.

Manual Rolling Upgrade Summary

In a manual rolling upgrade, you upgrade the MapR software one node at a time so that the cluster as a whole remains operational throughout the process. The manual rolling upgrade requires you to:
  1. Perform pre-upgrade checks
  2. Perform a rolling upgrade of MapR Core
  3. Verify that all use cases are functional on the cluster
  4. Upgrade the MEP to 6.0.0
  5. Merge custom configuration settings
  6. Enable MapR 6.1.0 features
  7. Perform post-upgrade checks

The workflow later in this section provides more detail to help you get started with a manual rolling upgrade.

Considerations for Manual Rolling Upgrades

Before performing a manual rolling upgrade, note these considerations:
  • Rolling upgrades only upgrade MapR Core packages, not ecosystem components. A rolling upgrade of ecosystem components is not supported.
  • If you choose to do a rolling upgrade on a cluster with MapR Core and MapR ecosystem components, the ecosystem components will continue to work during the rolling upgrade as long as the ecosystem components are not updated. If you choose to upgrade MapR Core and ecosystem components together, the ecosystem components might not function properly during the upgrade process.
  • You can only perform a manual rolling upgrade from the following MapR versions:
    • MapR 5.2.x with MEP 3.0.1 or later
    • MapR 6.0.0 with MEP 5.0.x
    • MapR 6.0.1 with MEP 4.0.x or 4.1.x
  • If your cluster is running MapR 5.2.x but your MEP is not 3.0.1 or later (for example, you have MEP 2.0.3), you must upgrade to MEP 3.0.1 or later before you can do a rolling upgrade to MapR 6.1.0. See Upgrading MapR Ecosystem Packs.
  • If you want to use a manual rolling upgrade from a pre-5.2 release to MapR 6.1, you must do multiple rolling upgrades, one of which upgrades your cluster to a MapR / MEP combination that can upgrade directly to MapR 6.1.
  • After upgrading MapR Core to MapR 6.1.0, you must upgrade ecosystem components to MEP 6.0.0 or later, and this must be done before you enable MapR 6.1 features
