Brandon Li updated HDFS-5259:
-----------------------------
Attachment: HDFS-5259.003.patch
[~jingzhao], I played with the idea to avoid the copy and see the
special-altered-write logic leaked into other part of the whole write data path.
The special-altered-write is expected to happen rarely, so I am not sure if
it's worth it to make the code harder to read. I still uploaded the patch so
you can take a look.
> Support client which combines appended data with old data before sends it to
> NFS server

> The append does not work with some Linux client. The Client gets
> "Input/output Error" when it tries to append. And NFS server considers it as
> random write and fails the request.
