chen kai commented on SQOOP-951:
--------------------------------

Removing the parent path if exist sub dir ?  This will cause more splits

```
  private void scanSubDirectory(Path path, FileSystem fs, List<Path> pathList) throws IOException {
    FileStatus[] status = fs.listStatus(path);
    // remove parent path
    pathList.remove(path);
    for(FileStatus fstat : status) {
      if(fstat.isDir()) {
        pathList.add(fstat.getPath());
        scanSubDirectory(fstat.getPath(), fs, pathList);
      } else {
        pathList.add(fstat.getPath());
      }
    }
  }
```

> I am using sqoop-1.4.2 to export to Sql.
> --export-dir does not work when the dir being passed is the root of subdirectories. -export-dir is not doing any recursive lookup for files. It expects directory with files that you want export.
> It would be great if one could pass a directory with subdirectories.
> Example:
> The following command exports the data to Sql
> ~/sqoop-1.4.2.bin__hadoop-1.0.0/bin/sqoop export --connect jdbc:postgresql://ec2-XX-XXX-XXX-XXX.compute-1.amazonaws.com:XXXX/xxxxxxxxxxxxx --username xxxxxxxxxx --password xxxxxxxxxx --table ml_ys_log_gmt_daily_experiment_2 --export-dir =hdfs:///mnt/var/lib/hadoop/dfs/logs_daily_sanitized/dt=2013-02-01 --input-fields-terminated-by='\t' --lines-terminated-by='\n' --verbose --batch
> hadoop@domU-XX-XX-XX-XX-XX-XX:/mnt/var/lib/hadoop/steps/2$ hadoop fs -ls hdfs:///mnt/var/lib/hadoop/dfs/logs_daily_sanitized/dt=2013-02-01
