Ivan Mitic commented on HADOOP-9437:
------------------------------------
I see, thanks for double checking Chris!
OK, I have one more minor comment since we're changing the native code anyways.
To be semantically correct, we cannot assume that last error is properly set
when we call the CRT rename API (its undocumented). Can we instead call
[MoveFile|http://msdn.microsoft.com/en-us/library/windows/desktop/aa365239(v=vs.85).aspx]
on Windows? (this is what rename does internally) Feel free to comment back
with your take.
> TestNativeIO#testRenameTo fails on Windows due to assumption that POSIX errno
> is embedded in NativeIOException

> HDFS-4428 added a detailed error message for failures to rename files by
