Colin Patrick McCabe updated HDFS-4258:
---------------------------------------

    Resolution: Duplicate
        Status: Resolved  (was: Patch Available)

I think this JIRA / patch has gotten a bit stale, since INode IDs are already 
in, as well as HDFS-6294, which addressed the issues we had with moving files 
that were open for write.  I'm marking this as a dupe of HDFS-6294.  Feel free 
to reopen if there's something more we should do here.

> When a being written file or it's ancestor directories is renamed, the path 
> in the file lease is also renamed.  Then the writer of the file usually will 
> fail since the file path in the writer is not updated.
> Moreover, I think there is a bug as follow:
> # Client writes 0's to F_0="/foo/file" and writes 1's to F_1="/bar/file" at 
> the same time.
> # Rename /bar to /baz
> # Rename /foo to /bar
> Then, writing to F_0 will fail since /foo/file does not exist anymore but 
> writing to F_1 may succeed since /bar/file exits as a different file.  In 
> such case, the content of /bar/file could be partly 0's and partly 1's.
