Workflow: Offline Manual Upgrade from Release 6.1 to 6.2

This page summarizes the steps for upgrading from release 6.1 to release 6.2 by using the offline manual 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.

Note: This workflow assumes that the cluster to be upgraded is running release 6.1.0 with MEP 6.3.1 (or later MEP 6.3.x), and the cluster operating system is one of the following:

Offline Manual Upgrade Summary

In an offline manual upgrade, cluster processes and the jobs that depend on them are stopped on all nodes so that packages can be updated. The offline upgrade process is simpler than a rolling upgrade, and usually completes faster. The offline manual upgrade requires you to:
  1. Perform pre-upgrade checks.
  2. Shut down the cluster.
  3. Upgrade core to 6.2.0.
  4. Upgrade the MEP to 7.x.
  5. Merge custom configuration settings.
  6. Start the cluster and perform post-upgrade checks.
  7. Enable MapR 6.2.0 features.

The workflow later on this page provides more detail to help you get started with an offline manual upgrade.

Considerations for Offline Manual Upgrades

Before performing an offline manual upgrade, note the following considerations:
Note: After upgrading core to MapR 6.2.0, you must upgrade ecosystem components to a MEP that is compatible with release 6.2.0. This must be done before you enable release 6.2.0 features. To determine the compatible MEPs, see MEP Support and Lifecycle Status.
  • You can perform an offline upgrade to release 6.2.0 only from release 6.1.x.
  • The offline upgrade procedure requires an outage of the entire cluster. During the maintenance window, the administrator:
    • Stops all jobs on the cluster.
    • Stops all cluster services.
    • Upgrades packages on all nodes (which can be done in parallel).
    • Brings the cluster back online at once.
