Upgrade Checklist

Performing an Upgrade

Perform the following on each node:

  1. Shut down all Dremio executors (including any YARN provisioned nodes, if any).

  2. Shut down Dremio coordinator nodes.

  3. On the master node: Make a copy of the metadata directory

  4. Upgrade to new RPM:

    sudo yum install dremio-<VERSION>.rpm
  5. On master coordinator: Execute the upgrade script as the user running Dremio:

    /opt/dremio/bin/dremio-admin upgrade
  6. Start Dremio coordinators, then start executors.

  7. Perform a backup on the new version.
