[jira] [Created] (HDFS-10531) Add EC policy and storage policy
related usage summarization function to dfs du command
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
