rumen should be able to filter and fold job traces
--------------------------------------------------

                 Key: MAPREDUCE-934
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-934
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Dick King


The rumen command line creates job traces from job history logs.  These job traces are read
by the rumen runtime system at the behest of other applications.  We should add a command
line tool to rumen to manipulate a job trace in various ways to modify a workload:

* overlap job trace segments to increase the workload
* extract a short segment from a long job trace
* stretch out job traces to dilute the workload
