[jira] [Created] (MAPREDUCE-4900) Dynamic configuration for task slots on TT

Junping Du created MAPREDUCE-4900:
-------------------------------------

             Summary: Dynamic configuration for task slots on TT
                 Key: MAPREDUCE-4900
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4900
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: resourcemanager, tasktracker
            Reporter: Junping Du
            Assignee: Binglin Chang


The current Hadoop MRV1 resource management logic assumes per node slot number is static during the lifetime of the TT process. Allowing run-time configuration on per node slot will give us finer granularity of resource elasticity. This allows Hadoop workloads to coexist with other workloads on the same hardware efficiently, whether or not the environment is virtualized.
For more background or design details of this effort, please refer proposal in HADOOP-9165.
