> TestKosmosFileSystem has some test cases that try to verify paths under /tmp/test/. If a user is running ant test on a system that is shared, this could result in test failures if these paths are created by another user who has used the system. The test cases can be modified to either use one of the standard data directories set up for tests by Hadoop, or they can atleast append the user name when referring to these directories, like /tmp/test-<username>/.
