Log Context

Log”{} move file [{}] size: [{}]” classname is MultiDataPathUpgrader.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                         Files.createDirectories(targetDir);
                        for (Path file : stream) {
                            if (IndexWriter.WRITE_LOCK_NAME.equals(file.getFileName().toString()) || Files.isDirectory(file)) {
                                continue; // skip write.lock
                            }
                            logger.info("{} move file [{}] size: [{}]"; shard; file.getFileName(); Files.size(file));
                            final Path targetFile = targetDir.resolve(file.getFileName());
                            /* We are pessimistic and do a copy first to the other path and then and atomic move to rename it such that
                               in the worst case the file exists twice but is never lost or half written.*/
                            final Path targetTempFile = Files.createTempFile(targetDir; "upgrade_"; "_" + file.getFileName().toString());
                            Files.copy(file; targetTempFile; StandardCopyOption.COPY_ATTRIBUTES; StandardCopyOption.REPLACE_EXISTING);
