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.
