Extending to Matt D and others answers  the command can be till Apache Hadoop 3 0 0  hadoop fs -du  -s   -h   -v   -x  URI  URI        It displays sizes of files and directories contained in the given directory or the length of a file in case it s just a file    Options     The -s option will result in an aggregate summary of file lengths being displayed  rather than the individual files  Without the -s option  the calculation is done by going 1-level deep from the given path  The -h option will format file sizes in a human-readable fashion  e g 64 0m instead of 67108864  The -v option will display the names of columns as a header line  The -x option will exclude snapshots from the result calculation  Without the -x option  default   the result is always calculated from all INodes  including all snapshots under the given path    du returns three columns with the following format    -------------------------------------------------------------------      size     disk space consumed with all replicas     full path name      -------------------------------------------------------------------      Example command  hadoop fs -du  user hadoop dir1        user hadoop file1       hdfs   nn example com user hadoop dir1   Exit Code  Returns 0 on success and -1 on error  source  Apache doc

hadoop fs -du -s -h  path to dir displays a directory s size in readable form

User · Answer

Command Should be hadoop fs -du -s -h  dirPath   -du  -s   -h           Show the amount of space  in bytes  used by the files that match the specified   file pattern   -s   Rather than showing the size of each individual file that matches the         pattern  shows the total  summary  size  -h   Formats the sizes of files in a human-readable fashion rather than a number of bytes   Ex MB GB TB etc   Note that  even without the -s option  this only shows size summaries one level deep into a directory   The output is in the form      size    name full path

When trying to calculate the total of a particular group of files within a directory the -s option does not work  in Hadoop 2 7 1   For example   Directory structure   some dir  abc txt      count1 txt   count2 txt   def txt       Assume each file is 1 KB in size  You can summarize the entire directory with   hdfs dfs -du -s some dir 4096 some dir   However  if I want the sum of all files containing  count  the command falls short   hdfs dfs -du -s some dir count  1024 some dir count1 txt 1024 some dir count2 txt   To get around this I usually pass the output through awk   hdfs dfs -du some dir count    awk    total   1   END   print total    2048
