[jira] Created: (MAPREDUCE-682) Reserved tasktrackers should be removed when a node is globally blacklisted

Reserved tasktrackers should be removed when a node is globally blacklisted
---------------------------------------------------------------------------

                 Key: MAPREDUCE-682
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-682
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobtracker
    Affects Versions: 0.21.0
            Reporter: Hemanth Yamijala


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.
