Zhe Zhang commented on HDFS-8898: --------------------------------- Quick note that I'm working on backporting HDFS-10744 to branch-2.7; since this change is not in branch-2.7, the overlapping part won't be backported. If someone plans to backport this to branch-2.7, please remember to add the optimization from HDFS-10744. > Create API and command-line argument to get quota and quota usage without > detailed content summary > -------------------------------------------------------------------------------------------------- > > Key: HDFS-8898 > URL: https://issues.apache.org/jira/browse/HDFS-8898 > Project: Hadoop HDFS > Issue Type: Bug > Components: fs > Reporter: Joep Rottinghuis > Assignee: Ming Ma > Fix For: 2.8.0, 3.0.0-alpha1 > > Attachments: HDFS-8898-2.patch, HDFS-8898-3.patch, HDFS-8898-4.patch, > HDFS-8898-5.patch, HDFS-8898-6.patch, HDFS-8898-branch-2.patch, > HDFS-8898.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
