To resolve this issue, you can try the following: 1) Check the Elasticsearch configuration files for any errors. 2) Restart the problematic node or the entire cluster. 3) If the problem persists, consider restoring from a backup. 4) If data corruption is suspected, you may need to rebuild the index. Always ensure that your data is regularly backed up to prevent loss.

 throw new ElasticsearchException("No node meta data at " + dataPath);
 }  final String nodeId = nodeMetadata.nodeId();
 final String index = shardPath.getShardId().getIndexName();
