> Key: NIFI-15693
> URL: https://issues.apache.org/jira/browse/NIFI-15693
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework, Security
> Affects Versions: 2.7.0, 2.8.0, 2.7.1, 2.7.2
> Reporter: David Handermann
> Assignee: David Handermann
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Following recent refactoring of the {{FileUserGroupProvider}} to use DOM
> instead of JAXB for parsing XML files, flow synchronization between cluster
> nodes can fail when the users.xml configuration is empty.
> On initial load, the AuthorizedUserGroups record object contains empty
> immutable Lists of users and groups when the local users.xml configuration is
> empty. The synchronization process calls {{forciblyInheritFingerprint}} on
> {{FileUserGroupProvider}} which can result in a
> {{FlowSynchronizationException}} caused by an
> {{UnsupportedOperationException}} on the empty immutable Lists in memory.
