mapreduce.jobtracker.taskscheduler.maxrunningtasks.perjob can not works either.
Forgot to mention, I'm using hadoop-2.3.0-cdh5.1.0. I greped the source code, mapred.jobtracker.taskScheduler.maxRunningTasksPerJob is only available in src/hadoop-mapreduce1-project/src/mapred/org/apache/hadoop/mapred/LimitTasksPerJobTaskScheduler.java. I think it's compatible with YARN's scheculer.
