Cluster Configuration Variables Reference#

This page lists every cluster configuration key declared in the Hopsworks server source code, with its type and default value. Descriptions are not included here. The source declarations carry no description field, so adding one would mean inventing text that was never reviewed against the actual behaviour of the setting. Adding descriptions is a planned enhancement, pending a source-side change that adds a description argument to the settings declarations.

Some defaults below are computed Java expressions rather than literal values, for example a reference to a constant defined in another class. Those rows show the raw expression and are marked as computed rather than showing a guessed value. A small number of keys are declared independently in more than one source file with their own default value. Those are shown as separate rows and marked as duplicates rather than merged into one, since the two declarations can drift apart.

See Cluster Configuration for how to view and change these variables from the Hopsworks UI.
