      Description

      Size of cluster is 350 NMs. I have topology.node.switch.mapping.impl set to enable rack-locality. Ran randomwriter/sort and scan jobs. Both jobs ran completed successfully.

      On Job client sort job says :

      Launched map tasks=16800
      Launched reduce tasks=700
      Other local map tasks=10
      Rack-local map tasks=16790
      

      JobHistory files also don't have information about Data Local Maps.

      There used to be information about data local maps before, till about a month back, like so:

      For sort with 349 NMs :

      Launched map tasks=16754 
      Launched reduce tasks=700
      Other local map tasks=48
      Data-local map tasks=16459
      Rack-local map tasks=248
