------------------------------------------
I looked at the code and it looks good. +1.
I wonder if this patch is needed for 0.17. It would be nice if you can run the
unit test on the 0.17 branch to determine if this bug exists in 0.17 as well.
> NameNode does not restart if parent directory of a "FileUnderConstruction" is
