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 find  this method influence it ;

protected StageInput uploadSegmentDataFiles(final String localPath, final String remotePath) {

if (!this.table.isHivePartitionTable()) {
final File[] files = new File(localPath).listFiles();
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 files is null ;
