Description

For the lines like:

Job JOBID="job_200803072233_0001" FINISH_TIME="1204929332820" JOB_STATUS="SUCCESS" FINISHED_MAPS="24" FINISHED_REDUCES="15" FAILED_MAPS="0" FAILED_REDUCES="0" COUNTERS="Job Counters .Launched map tasks=24,Job Counters .Launched reduce tasks=15Map-Reduce Framework.Map input records=2894276,Map-Reduce Framework.Map output records=2894276,Map-Reduce Framework.Map input bytes=3227015845,Map-Reduce Framework.Map output bytes=3232268034,Map-Reduce Framework.Combine input records=0,Map-Reduce Framework.Combine output records=0,Map-Reduce Framework.Reduce input groups=2526981,Map-Reduce Framework.Reduce input records=2894276,Map-Reduce Framework.Reduce output records=2894276"

The extracted value for COUNTERS is

Job Counters .Launched map tasks

which is clearly wrong.
