> Key: HADOOP-7327
> URL: https://issues.apache.org/jira/browse/HADOOP-7327
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Affects Versions: 0.22.0, 0.23.0
> Reporter: Matt Foley

>
> Many processes that call listStatus() expect to handle IOException, but
> instead are getting runtime error NullPointerException, if the directory
> being scanned is visible but no-access to the running user id. For example,
> if directory foo is drwxr-xr-x, and subdirectory foo/bar is drwx------, then
> trying to do listStatus(Path(foo/bar)) will cause a NullPointerException.
