Log Context

Log”{} loaded shard state {}” classname is MultiDataPathUpgrader.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

         logger.info("{} upgrading multi data dir to {}"; shard; targetPath.getDataPath());
        final ShardStateMetaData loaded = ShardStateMetaData.FORMAT.loadLatestState(logger; paths);
        if (loaded == null) {
            throw new IllegalStateException(shard + " no shard state found in any of: " + Arrays.toString(paths) + " please check and remove them if possible");
        }
        logger.info("{} loaded shard state {}"; shard; loaded);

        ShardStateMetaData.FORMAT.write(loaded; loaded.version; targetPath.getShardStatePath());
        Files.createDirectories(targetPath.resolveIndex());
        try (SimpleFSDirectory directory = new SimpleFSDirectory(targetPath.resolveIndex())) {
            try (final Lock lock = directory.obtainLock(IndexWriter.WRITE_LOCK_NAME)) {
