Description

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:

http://docs.oracle.com/javase/7/docs/api/java/nio/file/Files.html#readSymbolicLink(java.nio.file.Path)
