Phil Zampino commented on KNOX-1331:
------------------------------------
The issue is that you're starting with an XML provider configuration file. The
XML support is really a remnant of the iterative development of the dynamic
topology generation feature. It is supported, but the intent is for admins to
use JSON or YAML. Thus, the UI, when asked to update an XML provider
configuration, will actually replace it with JSON. The issue you are seeing is
a result of this; the UI is attempting to delete the original XML file, so it
can replace it with the JSON equivalent, but the provider configuration is
already referenced by one or more descriptors, so the deletion is not permitted.
It's possible that this conflict could be avoided.
