Performing a Maintenance Update

Perform a maintenance update when you want to upgrade to a new patch version of MapR Core or apply a patch.

A maintenance update is an update to your installed MapR software that does not require configuration-file changes. Performing a maintenance update has no effect on the ecosystem packages (MEP components). You perform a maintenance update when you want to do either or both of the following:
  • Update to a new patch version of MapR Core. For example, you can perform a maintenance update to change your MapR Core version from MapR 5.2 to MapR 5.2.1. You cannot use a maintenance update to change your MapR Core version from a minor version, such as 5.0, to another minor version, such as 5.2. The Version Upgrade button is used for minor-version upgrades. The Version Upgrade button also permits an upgrade to a patch version of MapR Core.
  • Apply a patch. The Maintenance Update page is one of several installer screens that offer the Patch file option. See Applying a Patch Using the MapR Installer.
Note: The maintenance update is an offline update (not a rolling update).
You perform a maintenance update using the MapR Installer. To perform a maintenance update:
  1. Update the MapR Installer if necessary. The maintenance update feature is available only with MapR Installer 1.5 or later.
  2. Prepare the cluster for a maintenance update by referring to one or both of these topics:
  3. Start the MapR Installer. For more information, see MapR Installer.
  4. Click the Maintenance Update button.
  5. Change the MapR Core Version, or install a MapR Core patch, or both.
  6. Click Next to complete the update.
