Applying a Patch for an Ecosystem Component

Patches for ecosystem components are handled differently from patches for Data Fabric core software.

About Patches for Ecosystem Components

Ecosystem components are updated as a package rather than a patch file. While core patches typically include a prefix such as mapr-patch or mapr-patch-client, ecosystem patches are delivered as a new package and do not use the core patch mechanism.

To identify an ecosystem patch package, look for the component name in the patch name. For example: 
mapr-livy-0.7.0.304.202309110421-1.noarch.rpm
Then use the steps on this page to update the currently installed package. The steps on this page use the Livy component as an example.

Applying the Patch

To apply the patch:
  1. On all nodes where the ecosystem component is running, stop the service for the component. For example:
    maprcli node services -name livy -action stop -nodes <ip_address>
  2. Before upgrading, check to see if other actions are needed. For example, you might want to back up configuration files for a component before upgrading. For more information, review the pre-upgrade steps for the component in Preparing to Upgrade the Ecosystem Pack.
  3. Use the following commands to upgrade the currently installed package for the component. For example:
    • On RHEL / CentOS or SLES:
      rpm -U <path to new package>
    • On Ubuntu: 
      dpkg -i <path to new package>
  4. Run configure.sh to update the configuration for the new package:
    $ /opt/mapr/server/configure.sh -R --noRecalcMem
  5. On all nodes where the service is installed, start the service:
    maprcli node services -name livy -action start -nodes <ip_address>
