Kengo Seki commented on HADOOP-9769:
------------------------------------
[~ajisakaa] thanks for your comment.
bq. I'm thinking we can remove Stat.isAvailable since Stat.getFileStatus is
available from all platforms.
Probably, {{Files.readAttributes(Paths.get(path.toString()),
PosixFileAttributes.class)}} raises {{UnsupportedOperationException}} on
Windows. So isAvailable is still needed and getFileStatus is not platform
independent yet.
bq. In addition, Stat can be removed and Stat.getFileStatus can be moved into
RawLocalFileSystem.
I'd like to do so. And on HADOOP-11935, [~cmccabe] suggests as follows. I'll
refer to it. I think these are very similar issues.
bq. +1 for using java.nio.file on Linux. On Windows we can use winutils like
always. The nice thing is, we won't need multiple code paths. The native
library is mandatory on Windows, and nio will always be available on Linux.

>
> HADOOP-9652 introduces a new class which shells out to stat(1) because of the
> lack of lstat(2) in Java 6. Java 7 has support for reading symlink targets
> via {{Files#readSymbolicLink}}.
> When Hadoop drops Java 6 support, let's use this more portable method instead.
> See:
