I've added a test case to FSMainOperationsBaseTest. Also touched up a couple apparent errors in that unit test file, such as no @Test annotations on two testcases that work just fine and fast. > 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 > Priority: Minor > Attachments: hadoop-7327-1.patch, hadoop-7327-2.patch > > > 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. -- This message is automatically generated by JIRA.
