Before you begin reading this guide, we recommend you run Elasticsearch Error Check-Up which can resolve issues that cause many errors.

This guide will help you check for common problems that cause the log ” Update_mapping (dynamic) ” to appear. It’s important to understand the issues related to the log, so to get started, read the general overview on common issues and tips related to the Elasticsearch concepts: cluster, mapping and metadata.

Advanced users might want to skip right to the common problems section in each concept or try running the Check-Up which analyses ES to pinpoint the cause of many errors and provides suitable actionable recommendations how to resolve them (free tool that requires no installation).

Log Context

Log “[{}] update_mapping [{}] (dynamic)” classname is MetaDataMappingService.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 
                    // build the updated mapping source
                    if (logger.isDebugEnabled()) {
                        logger.debug("[{}] update_mapping [{}] (dynamic) with source [{}]"; index; type; updatedMapper.mappingSource());
                    } else if (logger.isInfoEnabled()) {
                        logger.info("[{}] update_mapping [{}] (dynamic)"; index; type);
                    }

                    builder.putMapping(new MappingMetaData(updatedMapper));
                    dirty = true;
                } catch (Throwable t) {
