> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: jobtracker
> Affects Versions: 0.21.0

>
> When support was added to reserve tasktrackers for high RAM jobs per
> MAPREDUCE-516, we missed removing reservations on tasktrackers that are
> globally blacklisted. This is not a major concern, just that the reservation
> might cause the job to finish a little later than if the reservation is
> removed when the blacklisting happens.
