The way to check a HDFS directory's size?

Question

I know du -sh in common Linux filesystems. But how to do that with HDFS?

Answer 1

hdfs dfs -count

info from man page:

-count [-q] [-h] [-v] [-t []] [-u]  ... :
  Count the number of directories, files and bytes under the paths
  that match the specified file pattern.  The output columns are:
  DIR_COUNT FILE_COUNT CONTENT_SIZE PATHNAME
  or, with the -q option:
  QUOTA REM_QUOTA SPACE_QUOTA REM_SPACE_QUOTA
        DIR_COUNT FILE_COUNT CONTENT_SIZE PATHNAME
