>          Components: mapred
>    Affects Versions: 0.19.0

> Currently we have a notion of map-{setup|cleanup} TIP and reduce-{setup|cleanup} TIP
of which only 1 setup and cleanup tasks are picked by the JobInProgress. Also a lot of state-maintenence
of these TIPs are done by the JobInProgress itself, outside of the more logical place i.e.
> We really should rework this to have a single setup and cleanup task which isn't associated
with a map or reduce task i.e. into separate task _types_. What we have currently is quite
ungainly and hard to maintain.
