> 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.
