    Description

      An uberized job fails if the job classloader is enabled and the job needs to use the thread context classloader to load a class. Some example error in the log:

      2015-03-23 23:28:34,675 INFO [main] org.apache.hadoop.mapreduce.v2.util.MRApps: Creating job classloader
      ...
      2015-03-23 23:28:42,096 ERROR [uber-SubtaskRunner] cascading.provider.ServiceLoader: unable to find service class: cascading.tuple.hadoop.collect.HadoopTupleMapFactory, with exception: java.lang.ClassNotFoundException: cascading.tuple.hadoop.collect.HadoopTupleMapFactory
