      Added the ability to kill process trees transgressing memory limits. TaskTracker uses the configuration parameters introduced in HADOOP-3759. In addition, mapred.tasktracker.taskmemorymanager.monitoring-interval specifies the interval for which TT waits between cycles of monitoring tasks' memory usage, and mapred.tasktracker.procfsbasedprocesstree.sleeptime-before-sigkill specifies the time TT waits for sending a SIGKILL to a process-tree that has overrun memory limits, after it has been sent a SIGTERM.

    Description

      Sometimes user Map/Reduce applications can get extremely memory intensive, maybe due to some inadvertent bugs in the user code, or the amount of data processed. When this happens, the user tasks start to interfere with the proper execution of other processes on the node, including other Hadoop daemons like the DataNode and TaskTracker. Thus, the node would become unusable for any Hadoop tasks. There should be a way to prevent such tasks from bringing down the node.
