9bd6a8d403 is described below
commit 9bd6a8d40314626c9d1da0bec2f807640aff253d
Author: Christopher Tubbs <ctubb...@apache.org>
AuthorDate: Wed Jul 24 09:05:52 2024 -0400
Make isPropertySet work for fixed properties (#4752)
* Add more comments (including javadocs) to explain fixed properties
* Add the ability to track whether a fixed property was set on startup
by recording the runtime state of whether a user had set the property
or not
* Update AccumuloConfigurationIsPropertySetTest to ensure that the
runtime properties behavior is working correctly
* Also, rename a scan server property enum to match the others
This fixes #3529
