> The new shuffle assumes that the number of maps is correct. The new JobSubmitter sets the old value. Something misfires in the middle causing:
> 09/12/01 00:00:15 WARN conf.Configuration: mapred.job.split.file is deprecated. Instead, use mapreduce.job.splitfile
> 09/12/01 00:00:15 WARN conf.Configuration: mapred.map.tasks is deprecated. Instead, use mapreduce.job.maps
> But my reduces got stuck at 2 maps / 12 when there were only 2 maps in the job.
