Chuan Liu commented on HADOOP-9437:
-----------------------------------
I am also +1 on using native calls over CRT functions. The behaviors of CRT
functions are more unpredictable in my experience.
> 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
> embedding the POSIX errno in the {{NativeIOException}}. On Windows, the
> mapping of errno is not performed, so the errno enum value will not be
> present in the {{NativeIOException}}.
