>             Project: Hadoop Common
>          Issue Type: Sub-task

> This problem showed when trying to use FileUtils.sizeOfDirectory() of a directory that
contained a symlink to a file that did not exist. I got the exception:
> java.lang.IllegalArgumentException: /tmp/test/link does not exist
> 	at org.apache.commons.io.FileUtils.sizeOf(FileUtils.java:2413)
> 	at org.apache.commons.io.FileUtils.sizeOfDirectory(FileUtils.java:2479)
> And /tmp/test/link is here linking to a file that do not exist.
> The trace comes from a unit test that looks like:
> assertTrue(FileUtils.sizeOfDirectory(new File("/tmp/test/")) > 0);
> I would expect that either isSymlink() reported true even though the link is to a file
that do not exist or sizeOfDirectory() should not bail out when encountering non-existing
files.
