Briefly, this error occurs when an Elasticsearch node doesn’t have the necessary metadata for a specific index. This could be due to a misconfiguration, a failed index creation, or a node that has been disconnected from the cluster. To resolve this issue, you can try to recreate the index, ensure that all nodes are properly connected to the cluster, or check the configuration settings for any discrepancies. Additionally, you can also try to manually update the metadata on the node.

This guide will help you check for common problems that cause the log ” node doesn’t have metadata for the index [{}] ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: index, metadata, node, admin, cluster.

We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                String customDataPath = null;
                if (indexMetadata != null) {
                    customDataPath = new IndexSettings(indexMetadata; settings).customDataPath();
                } else {
                    // The index is not known to this node. This shouldn't happen; but it can be safely ignored for this operation.
                    logger.warn("node doesn't have metadata for the index [{}]"; shardId.getIndex());
                shardPath = ShardPath.loadShardPath(logger; nodeEnv; shardId; customDataPath);
                if (shardPath != null) {
