Subject [jira] [Created] (HDFS-8898) Create API and command-line argument to get quota without need to get file and directory counts

Joep Rottinghuis created HDFS-8898:
--------------------------------------

             Summary: Create API and command-line argument to get quota without need to get
file and directory counts
                 Key: HDFS-8898
                 URL: https://issues.apache.org/jira/browse/HDFS-8898
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: fs
            Reporter: Joep Rottinghuis


On large directory structures it takes significant time to iterate through the file and directory
counts recursively to get a complete ContentSummary.
When you want to just check for the quota on a higher level directory it would be good to
have an option to skip the file and directory counts.

Moreover, currently one can only check the quota if you have access to all the directories
underneath. For example, if I have a large home directory under /user/joep and I host some
files for another user in a sub-directory, the moment they create an unreadable sub-directory
under my home I can no longer check what my quota is. Understood that I cannot check the current
file counts unless I can iterate through all the usage, but for administrative purposes it
is nice to be able to get the current quota setting on a directory without the need to iterate
through and run into permission issues on sub-directories.
