Subject [jira] [Created] (HDFS-10531) Add EC policy and storage policy related usage summarization function to dfs du command
Date Wed, 15 Jun 2016 06:00:17 GMT
GAO Rui created HDFS-10531:
------------------------------

             Summary: Add EC policy and storage policy related usage summarization function
to dfs du command
                 Key: HDFS-10531
                 URL: https://issues.apache.org/jira/browse/HDFS-10531
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: GAO Rui


Currently du command output:
{code}
        [ ~]$ hdfs dfs -du  -h /home/rgao/
        0      /home/rgao/.Trash
        0      /home/rgao/.staging
        100 M  /home/rgao/ds
        250 M  /home/rgao/ds-2
        200 M  /home/rgao/noECBackup-ds
        500 M  /home/rgao/noECBackup-ds-2
{code}

For hdfs users and administrators, EC policy and storage policy related usage summarization
would be very helpful when managing storages of cluster. The imitate output of du could be
like the following.
{code}
        [ ~]$ hdfs dfs -du  -h -t( total, parameter to be added) /home/rgao
         
        0      /home/rgao/.Trash
        0      /home/rgao/.staging
        [Archive] [EC:RS-DEFAULT-6-3-64k] 100 M  /home/rgao/ds
        [DISK] [EC:RS-DEFAULT-6-3-64k]     250 M  /home/rgao/ds-2
        [DISK] [Replica]     200 M  /home/rgao/noECBackup-ds
        [DISK] [Replica]     500 M  /home/rgao/noECBackup-ds-2
         
        Total:
         
        [Archive][EC:RS-DEFAULT-6-3-64k]  100 M
        [Archive][Replica]                                0 M
        [DISK] [EC:RS-DEFAULT-6-3-64k]     250 M
        [DISK] [Replica]                               700 M  
     
        [Archive][ALL]                                 100M
        [DISK]    [ALL]                                  950M
        [ALL]     [EC:RS-DEFAULT-6-3-64k]    350M
        [ALL]     [Replica]                              700M
{code}
