Subject [jira] Commented: (HADOOP-6080) Handling of Trash with quota
Date Tue, 30 Jun 2009 16:56:47 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6080?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12725696#action_12725696
] 

Jakob Homan commented on HADOOP-6080:
-------------------------------------

bq. Should we consider excluding trash for files deleted from /tmp (ie make -skipTrash implicit
when deleting from /tmp.)? 
I'm not a fan of special cases for certain directories, even for /tmp, and particularly when
we're already straying away from the posix world with the trash feature.  Minimizing surprise
seems a good goal, and I'd be very surprised if I were accustomed to explicitly skipping the
trash when I want and discovering something I had expected to be trashed had been helpfully
nuked by the system.
