> In hadoop trunk, org.apache.hadoop.fs.FileSystem.listStatus() is declared to throws both FileNotFoundException and IOException. The former (FileNotFoundException) is currently not caught when BspCase.setup() looks for the GiraphJob.ZOOKEEPER_MANAGER_DIR_DEFAULT directory in order to delete it. The listStatus() call throws FileNotException if this directory does not exist and causes several tests to fail when using Hadoop trunk. This exception should be caught and ignored during setup(), since it's not an error for this directory not to exist.
