Applying a Patch

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

ATTENTION
Note the following before you proceed:
  • A fabric installed by using the legacy installer must be upgraded by using the legacy installer only. The legacy installer does not install the Keycloak service. You must use your organization's Keycloak service for production environments. Similarly, the life cycle of a fabric installed by using the Data Fabric UI should be solely managed by using the Data Fabric UI. If you still go ahead and add patch by using the legacy installer (the installer is installed on all the nodes of the fabric), future updates/upgrades to the fabric will remove the patch as the Data Fabric UI does not know the patch was installed.
  • The mapr-keycloak package available with HPE Ezmeral Data Fabric is only a placeholder service in the Data Fabric UI, and is not recommended for a production environment. You must use your organization's Keycloak service in a production environment. The legacy installer does not install the Keycloak service.
