The trace generator should test operation on the current format by building a test case that
runs an ad hoc cluster

                 Key: MAPREDUCE-1479
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1479
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
    Affects Versions: 0.22.0
            Reporter: Dick King
             Fix For: 0.22.0


Rumen's trace generator, built in final form when we install MAPREDUCE-1309 , has features
that can parse a history event log in the current format.  The testing story on that feature
is not good.  We can improve it by writing a test case that builds a local single-node cluster,
runs a carefully crafted map/reduce job on that cluster, runs the trace generator on the resulting
job tracker log, and finally tests the trace for correctness.
