Allen Wittenauer resolved MAPREDUCE-138.
----------------------------------------
Resolution: Won't Fix
Stale.
> Rework job-setup and job-cleanup tasks
> --------------------------------------
>
> Key: MAPREDUCE-138
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-138
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Arun C Murthy
> Assignee: Devaraj Das
>
> 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.
> TaskInProgress.
> 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.
