but there no stage_data directory and data not mv to stage_data when flink app commit;

i debug code find in CarbonWriter.java file protected StageInput uploadSegmentDataFiles(final String localPath, final String remotePath) {

if (!this.table.isHivePartitionTable()) {
 final *{color:#FF0000}File[] files = new File(localPath).listFiles();{color}*
 if (files == null) {
 LOGGER.error("files is null" );
 return null;
 }
 Map<String, Long> fileNameMapLength = new HashMap<>(files.length);
 for (File file : files) {
 fileNameMapLength.put(file.getName(), file.length());
 if (LOGGER.isDebugEnabled()) {
 LOGGER.debug(
 "Upload file[" + file.getAbsolutePath() + "] to [" + remotePath + "] start.");
 }
 try {
 CarbonUtil.copyCarbonDataFileToCarbonStorePath(file.getAbsolutePath(), remotePath, 1024);
 } catch (CarbonDataWriterException exception) {
 LOGGER.error(exception.getMessage(), exception);
 throw exception;
 }
 if (LOGGER.isDebugEnabled()) {
 LOGGER.debug("Upload file[" + file.getAbsolutePath() + "] to [" + remotePath + "] end.");
 }
 }
 return new StageInput(remotePath, fileNameMapLength);
} else {
 final List<StageInput.PartitionLocation> partitionLocationList = new ArrayList<>();
 final List<String> partitions = new ArrayList<>();
 uploadSegmentDataFiles(new File(localPath), remotePath, partitionLocationList, partitions);
 if (partitionLocationList.isEmpty()) {
 return null;
 } else {
 return new StageInput(remotePath, partitionLocationList);
 }
}

 the local path is a hdfs file so {color:#FF0000}files is null ;{color}
