MapTask should wait for the status reporting thread to die before invoking the TaskUmbilicalProtocol.done(taskid)

      Description

      Currently, the status reporting thread is sent an interrupt and immediately after that TaskUmbilicalProtocol.done() is invoked. A better thing to do is to wait for the thread to die before invoking done() otherwise it is possible that a status message just makes it through and then the Task is put in RUNNING state at the TaskTracker. This results in inconsistency about the runstate of a task at the TaskTracker's end.
