Matei Zaharia commented on MAPREDUCE-1258:
------------------------------------------
Dhruba let me know that it's fine to commit this to 0.21 too, because it's a
bug fix. I'll wait a day to see if there are any objections, and otherwise I'll
commit it.
> Fair scheduler event log not logging job info

> Key: MAPREDUCE-1258

> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: contrib/fair-share
> Affects Versions: 0.21.0
> Reporter: Matei Zaharia
> Assignee: Matei Zaharia
> Priority: Minor
> Fix For: 0.22.0

> The MAPREDUCE-706 patch seems to have left an unfinished TODO in the Fair
> Scheduler - namely, in the dump() function for periodically dumping scheduler
> state to the event log, the part that dumps information about jobs is
> commented out. This makes the event log less useful than it was before.
> It should be fairly easy to update this part to use the new scheduler data
> structures (Schedulable etc) and print the data.
