Subject [jira] Commented: (HADOOP-3938) Quotas for disk space management
Date Tue, 26 Aug 2008 18:34:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3938?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12625819#action_12625819

Robert Chansler commented on HADOOP-3938:

Sorry, I confused the issue. 

Create should not require any space quota. The quota should be checked only when a new block
is requested.

I'll attach a new version of the guide with the clarification!

> 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.
