the umbilical.done is called two times in case a task is finished.
The map and the reduce task implementation call done when in the last

But the tasktracker calls the the umbilical.done a second time in line
585.
You're right.
Is this a bug? I guess the jobtracker just ignores second time
fininshed tasks.
Should I open a bug report?
I don't think it causes any harm, but we might fix it anyway. I think
we should remove the call on TaskTracker.java:585. Note that under
LocalJobRunner.java done() is only called once, so I think the "extra"
call is the one in TaskTracker.java.
