Hi Why don't you provide a seed of random generator generated outside the task ? Then when the task fails, you can provide the same value stored somewhere outside. You could use the task configuration to do so.
I don't know anything about obtaining the task ID from within. regards Piotr 2009/6/18 Mark Desnoyer <mdesno...@gmail.com> > Hi, > > I was wondering if it's possible to get a hold of the task id inside a > mapper?
