[ http://issues.apache.org/jira/browse/HADOOP-432?page=comments#action_12436977 ] Doug Cutting commented on HADOOP-432: -------------------------------------
Perhaps the maximum size should be relative to the filesystem capacity, rather than absolute? Otherwise a reasonable default setting will be difficult. What is the public API? I think this should be a new FileSystem or DistributedFileSystem method, not a change to delete(). Perhaps it could be called moveToTrash(). Then we also need the ability to list the trash contents and undelete things. > 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
