* disable pre-emption.
* run two job with different priority in different queue at the same time
** yarn jar hadoop-mapreduce-examples-2.7.2.jar pi -Dyarn.app.priority=LOW
-Dmapreduce.job.queuename=QueueA -Dmapreduce.map.memory.mb=4096
-Dyarn.app.mapreduce.am.resource.mb=1536
-Dmapreduce.job.reduce.slowstart.completedmaps=1.0 10 1000000000000
** yarn jar hadoop-mapreduce-examples-2.7.2.jar pi -Dyarn.app.priority=HIGH
-Dmapreduce.job.queuename=QueueB -Dmapreduce.map.memory.mb=4096
