Examples of org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.JobControlCompiler.updateMROpPlan()

        //First job is just foreach with projection, mapper-only job, so estimate gets ignored
        Util.assertParallelValues(-1, -1, -1, 0, jobControl.getWaitingJobs().get(0).getJobConf());


        jcc.updateMROpPlan(jobControl.getReadyJobs());
        jobControl = jcc.compile(mrPlan, query);
        jcc.updateMROpPlan(jobControl.getReadyJobs());


        //Second job is a sampler, which requests and gets 1 reducer
        Util.assertParallelValues(-1, 1, -1, 1, jobControl.getWaitingJobs().get(0).getJobConf());


        jobControl = jcc.compile(mrPlan, query);

                    for (PhysicalOperator value : mro.phyToMRMap.get(key))
                        phyToMRMap.put(key, value);
            }
            
            
            int removedMROp = jcc.updateMROpPlan(new LinkedList<Job>());
            
            numMRJobsCompl += removedMROp;
