> Rename of Being Written Files
> -----------------------------
>
> Key: HDFS-4258
> URL: https://issues.apache.org/jira/browse/HDFS-4258
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs-client, namenode
> Affects Versions: 3.0.0
> Reporter: Tsz Wo (Nicholas), SZE
> Assignee: Brandon Li
> Attachments: HDFS-4258.patch, HDFS-4258.patch
>
>
> 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.
