---------------------------------------
Arun,
Haven't heard from you on this. As most of the changes are unrelated to the original issue, I'll mark this as resolved and work on a cleanup JIRA tomorrow unless you say otherwise?

> I'm looking now at my jobtracker's list of running reduce tasks. One of them is 120.05% complete, the other is 107.28% complete.
> I understand that these numbers are estimates, but there is no case in which an estimate of 100% for a non-complete task is better than an estimate of 99.99%, nor is there any case in which an estimate greater than 100% is valid.
> I suggest that whatever logic is computing these set 99.99% as a hard maximum.
