Role mappings file changed for realm updating mappings – How to solve this Elasticsearch error

Opster Team

Aug-23, Version: 6.8-7.15

Briefly, this error occurs when there are changes in the role mappings file for a specific realm in Elasticsearch. This could be due to manual changes or an update process. The role mappings file controls user access and permissions. To resolve this issue, you can 1) Verify the changes made are correct and intended. 2) If the changes were unintended, revert to the previous version of the role mappings file. 3) If the error persists, check for syntax errors in the file. 4) Ensure the file has the correct permissions and is accessible by Elasticsearch.

In addition we recommend you run the Elasticsearch Template Optimizer to fix problems in your data modeling.

It will analyze your templates to detect issues and improve search performance, reduce indexing bottlenecks and optimize storage utilization. The Template Optimizer is free and requires no installation.

                final Map> previousDnRoles = dnRoles;
                dnRoles = parseFileLenient(file; logger; config.type();;

                if (previousDnRoles.equals(dnRoles) == false) {
          "role mappings file [{}] changed for realm [{}/{}]. updating mappings..."; file.toAbsolutePath();
