    • Release Note:
      Jobtracker was modified to cleanup reservations created on tasktracker nodes to support high RAM jobs, when the nodes are blacklisted.

      Description

      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.
