Subject [jira] Updated: (HADOOP-3187) Quotas for name space management
Date Wed, 04 Jun 2008 18:10:46 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-3187?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Hairong Kuang updated HADOOP-3187:

    Release Note: 
The directory quota is a hard limit on the number of names in the tree rooted at that directory.
This jira allows an administrator to set quotas on individual directories explicitly. Newly
created directories have no associated quota. The largest quota is Long.Max_Value. A quota
of one forces a directory to remain empty.  File/directory creations fault if the quota would
be exceeded. Quotas stick to renamed directories; the rename operation 
faults if operation would result in a quota violation. The attempt to set a quota faults if
the directory would be in violation of the new quota. 
    Hadoop Flags: [Reviewed]
          Status: Patch Available  (was: Open)
