  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.

Writing Applications to Use the MapR PACC

This section describes a number of resources for developing applications to use the MapR PACC.

Developing applications to use the MapR PACC is the same as developing applications on other MapR-supported platforms. To get started, see these topics:

To build a container for your application that can leverage MapR Converged Data Platform services, you will create a Dockerfile referencing the MapR PACC which installs your application and its dependencies. You can then build and launch your application using the same runtime variables described later in this section.
