      Description

      When the TaskTracker is oedered to reinit by JobTracker, it will interrupt some threads and then reinit them, but TaskTracker does not interrupt TaskMemoryManager thread and create a new TaskMemoryManager thread again. I use the tool--jstack to find that(I reinit TaskTracker 3 times through JobTracker send TaskTrackerAction.ActionType.REINIT_TRACKER).
