I'd start with investigating this:
ERROR security.UserGroupInformation: PriviledgedActionException as:hduser cause:org.apache.hadoop.mapred.InvalidInputException: Input path does not exist: file:/user/hduser/gutenberg
It seems it causes the problem. Are you sure this is the proper path? If so, you may not have the privilage to access to it. Later on I would try to eliminate as much WARN as I can.
