Re-syncing mappings with cluster state for types – How to solve this Elasticsearch error

Opster Team

Aug-23, Version: 1.7-1.7

Briefly, this error occurs when Elasticsearch is trying to synchronize the mappings (schema definitions) of your indices with the current state of the cluster. This could be due to changes in the mappings or inconsistencies between nodes. To resolve this issue, you can try the following: 1) Ensure all nodes in the cluster are running the same version of Elasticsearch. 2) Check your mappings for errors or inconsistencies and correct them. 3) If the problem persists, consider re-indexing your data with the correct mappings.

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.

                    dirty = true;
                } catch (Throwable t) {
                    logger.warn("[{}] failed to refresh-mapping in cluster state; types [{}]"; index; refreshTask.types);
            } else if (task instanceof UpdateTask) {
