    Description

      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.
