Christophe Taton commented on HADOOP-1708:
------------------------------------------
I agree. At least in a short term, the semantics should remain as it is when
the file is not visible, meaning that a file being created cannot be deleted or
renamed before it is completed.
Ideally however, renaming and deletion should also work on file being created.
Renaming should not interfere with the file creation, while deletion should
prevent it to complete.
> make files visible in the namespace as soon as they are created

> In the current DFS implementation, a file appears in the namespace only when
> the creator closes the file. Also, if the namenode or the client dies before
> closing the file, the file never appears in the namespace.
> This issue will make files appear in the namespace as soon as it is created.
> Also, it will continue to remain in the namespace even if the creator dies
> before closing the file.
> This is related to HADOOP-89. It is different from HADOOP-89 because it does
> not attempt to make data visible as soon as it is written.
