Hadoop Flags: Reviewed
Release Note:
Introduced directory quota as hard limits on the number of names in the tree rooted at that directory. An administrator may set quotas on individual directories explicitly. Newly created directories have no associated quota. File/directory creations fault if the quota would be exceeded. The attempt to set a quota faults if the directory would be in violation of the new quota.
Resolution Date: 05/Jun/08 06:13 AM


 Description  « Hide
Create a quota mechanism for name space management.

Quota set at a directory by super user restricts that number of names in and below that directory.

Quota tested by create() and rename().

Hairong Kuang made changes - 04/Jun/08 06:10 PM
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.
