Subject [jira] Commented: (HADOOP-3938) Quotas for disk space management
Date Tue, 16 Sep 2008 18:18:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3938?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12631487#action_12631487

Konstantin Shvachko commented on HADOOP-3938:
---------------------------------------------

Imo, you should be able to start name-node with quotas turned off (in config) and then be
able to correct quotas for the faulty directory.
Does the patch allow that?
We should also check namespace quotas for the same problem.

> Directory quotas for bytes limit the number of bytes used by files in and below the directory.
Operation is independent of name quotas (HADOOP-3187), but the implementation is parallel.
Each file is charged according to its length multiplied by its intended replication factor.
