Colin Patrick McCabe updated HADOOP-9060:
-----------------------------------------
Issue Type: Sub-task (was: Bug)
Parent: HADOOP-10019
> isSymlink returns false for link to non-existing file
> -----------------------------------------------------
>
> Key: HADOOP-9060
> URL: https://issues.apache.org/jira/browse/HADOOP-9060
> Project: Hadoop Common
> Issue Type: Sub-task
> Environment: Kubuntu 12.10 commons-io 2.4
> Reporter: Daniel Bengtsson
>
> 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.
