Subject [jira] Commented: (HADOOP-3083) Remove lease when file is renamed
Date Mon, 24 Mar 2008 22:29:24 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3083?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12581701#action_12581701

Runping Qi commented on HADOOP-3083:

Actually I think you should repair the leases so that the existing lease holders can continue
writing to their files.

Here is  a use case.

say a client is writing to a file /xyz/parent_dir/dub_dir/file

Somebody performs a command like "hadoop dfs -rename  /xyz/parent /xyz/new_parent"

This operation should not cause the client to fail to continue writing the the file.
Otherwise, "hadoop dfs -rename dir1 dir2" will be a very dangerous operations

> When a file/directory is removed, the namenode should remove lease(s) for files that
were affected by the rename.
