[jira] [Created] (TEZ-2710) TEZ_TASK_SCALE_MEMORY_RESERVE_FRACTION should be configurable at vertex level

---------------------------------------

             Summary: TEZ_TASK_SCALE_MEMORY_RESERVE_FRACTION should be configurable at vertex level
                 Key: TEZ-2710
                 URL: https://issues.apache.org/jira/browse/TEZ-2710
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Rohini Palaniswamy


  Was trying to set TezConfiguration.TEZ_TASK_SCALE_MEMORY_RESERVE_FRACTION used by WeightedScalingMemoryDistributor at vertex level.  But it failed with

"tez.task.scale.memory.reserve-fraction is set at the scope of VERTEX, but it is only valid in the scope of AM"

 Even otherwise [~sseth] was telling me that vertex.setConf() does not work as it is supposed to and not taken into account with container reuse.
