dhruba borthakur updated HADOOP-4044:

    Attachment: symLink13.patch

Fixed findbugs warnings. Also fixed the reason for the unit test failure: FileSystem.exists()
was not implemented correctly in the earlier version of this patch.

> HDFS should support symbolic links. A symbolic link is a special type of file that contains
a reference to another file or directory in the form of an absolute or relative path and that
affects pathname resolution. Programs which read or write to files named by a symbolic link
will behave as if operating directly on the target file. However, archiving utilities can
handle symbolic links specially and manipulate them directly.
