Todd Lipcon commented on HADOOP-7478:
-------------------------------------
In trunk we have o.a.h.fs.Options.Rename.OVERWRITE. We could modify fs -put to
write to a .tmp file in the same directory, then rename with OVERWRITE to the
final destination.
> 0-byte files retained in the dfs while the FSshell -put is unsuccessful

> The process of putting file into dfs is approximately as follows:
> 1) create a file in the dfs
> 2) copy from one stream to the file
> But the problem is that the file is still retained in the dfs when the
> process 2) is terminated abnormally with unexpected exceptions,such as there
> is no DataNode alive.
