Cloudera recommends following the Cloudera Data Visualization (CDV) release cadence by
upgrading to the latest version as it becomes available. This practice ensures that your CDV
instances benefit from the latest security enhancements, bug fixes, and new
features.
This guide walks you through the considerations for performing
an upgrade, the available options, and the steps of the upgrade process.
Before initiating the upgrade, review the Known issues and limitations in Data Visualization
in the Release Notes for both the currently running version and the version to which you are
planning to upgrade. This step helps you understand any potential challenges, limitations,
or specific actions required for a successful upgrade.
Stop the application.
On the Applications page in CML/CDSW, click Actions > Stop to stop the selected CDV application.
Back up the SQLite metadata database.
Go to your project's Overview page and click New
Session.
When your session is running, click >_ Terminal Access above
the session log pane.
A terminal window opens, and its default working directory is
/home/cdsw, where all your project files reside.
Navigate to /home/cdsw/.arc.
This directory contains the CDV logs, files, settings, and the arcviz.db
database.
