Before you begin reading this guide, we recommend you try running the 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 ” Creating index. cause . shards . mappings ” 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, index, metadata and shards.

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 “[{}] creating index; cause [{}]; shards [{}]/[{}]; mappings {}” classname is MetaDataCreateIndexService.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 
                    MetaData newMetaData = MetaData.builder(currentState.metaData())
                            .put(indexMetaData; false)
                            .build();

                    logger.info("[{}] creating index; cause [{}]; shards [{}]/[{}]; mappings {}"; request.index(); request.cause(); indexMetaData.numberOfShards(); indexMetaData.numberOfReplicas(); mappings.keySet());

                    ClusterBlocks.Builder blocks = ClusterBlocks.builder().blocks(currentState.blocks());
                    if (!request.blocks().isEmpty()) {
                        for (ClusterBlock block : request.blocks()) {
                            blocks.addIndexBlock(request.index(); block);
