Description
The property's entry in mapred-default.xml is like so:
<property> <name>mapreduce.jobtracker.taskscheduler.maxrunningtasks.perjob</name> <value></value> <description>The maximum number of running tasks for a job before it gets preempted. No limits if undefined. </description> </property>
There is no mention that this is a property exclusive to the LimitTasksPerJob scheduler alone. The doc ought to be updated to note that unless there's a plan of reusing such a property (I do not see fair or capacity schedulers utilizing this, and they use their own configs).
