Subject [jira] Created: (MAPREDUCE-1684) ClusterStatus can be cached in CapacityTaskScheduler.assignTasks()
Date Wed, 07 Apr 2010 10:47:33 GMT
ClusterStatus can be cached in CapacityTaskScheduler.assignTasks()
------------------------------------------------------------------

                 Key: MAPREDUCE-1684
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1684
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: contrib/capacity-sched
            Reporter: Amareshwari Sriramadasu


Currently,  CapacityTaskScheduler.assignTasks() calls getClusterStatus() thrice: once in assignTasks(),
once in MapTaskScheduler and once in ReduceTaskScheduler. It can be cached in assignTasks()
and re-used.
