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
