[ http://issues.apache.org/jira/browse/HADOOP-432?page=comments#action_12436994 ] p sutter commented on HADOOP-432: ---------------------------------
Why not just keep everything, and reclaim the oldest-deleted when space is allocated for a new file? Benefits: - recycle bin data is kept for the longest time possible, - new files always take precendence over files in the recycle bin, - no independent deletion process is needed and best of all: - no new configuration parameters > support undelete, snapshots, or other mechanism to recover lost files > --------------------------------------------------------------------- > > Key: HADOOP-432 > URL: http://issues.apache.org/jira/browse/HADOOP-432 > Project: Hadoop > Issue Type: Improvement > Components: dfs > Reporter: Yoram Arnon > Assigned To: Wendy Chien > > currently, once you delete a file it's gone forever. > most file systems allow some form of recovery of deleted files. > a simple solution would be an 'undelete' command. > a more comprehensive solution would include snapshots, manual and automatic, > with scheduling options. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
