Examples of GiraphJob

org.apache.giraph.graph.GiraphJob
Limits the functions that can be called by the user. Job is too flexible for our needs. For instance, our job should not have any reduce tasks.
org.apache.giraph.job.GiraphJob
Generates an appropriate internal {@link Job} for using Giraph in Hadoop.Uses composition to avoid unwanted {@link Job} methods from exposureto the user.
