  You can apply a patch by using the MapR Installer, by using the command line (a manual process), or by using a MapR Installer Stanza.

Upgrading MapR Core Without the MapR Installer

If you installed the cluster without using the MapR Installer, you can upgrade without using the MapR Installer.

If the cluster that you want to upgrade was not installed using the MapR Installer, you can upgrade without using the MapR Installer. First, you perform an offline or rolling upgrade of the MapR core manually or using a script. Next, you configure the new version to enable support of MapR core features. Finally, you upgrade ecosystem components manually.

NOTE: Version 1.5 of the MapR Installer introduced commands to enable the installer database on MapR 5.2 clusters that were not installed using the MapR Installer. Enabling the installer database makes it possible to use the MapR Installer on these clusters. For more information, see Using probe and import to Generate the Installer Database.

When upgrading, you can install packages from the following sources:

The MapR internet repository
A local repository
Individual package files

Go to the next topic to begin setting up repositories.

When you are finished upgrading MapR core, you will need to follow the steps to upgrade the ecosystem components. See Upgrading the MEP Without the MapR Installer. Then return to this section.
