Failed to update-mapping in cluster state type – How to solve this Elasticsearch error

Opster Team

Aug-23, Version: 1.7-1.7

Briefly, this error occurs when Elasticsearch is unable to update the mapping of an index in the cluster state. This could be due to a variety of reasons such as incorrect mapping syntax, insufficient permissions, or a conflict with existing mappings. To resolve this issue, you can check and correct the mapping syntax, ensure the user has the necessary permissions, or delete and recreate the index with the correct mappings. If the issue persists, consider checking the Elasticsearch logs for more detailed error information.

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.

                    builder.putMapping(new MappingMetaData(updatedMapper));
                    dirty = true;
                } catch (Throwable t) {
                    logger.warn("[{}] failed to update-mapping in cluster state; type [{}]"; index; updateTask.type);
                }
            } else {
                logger.warn("illegal state; got wrong mapping task type [{}]"; task);
            }
        }
