FileSystem.listStatus() throws NullPointerException instead of IOException upon
access permission failure
---------------------------------------------------------------------------------------------------------
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
Assignee: 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.
