Hi,
  If I set the gather partitions on Tez, will that guarantee global ordering by doing below?

  Pipe groupby = new GroupBy(priorPipe, Fields.NONE, getSortFields(sort), sort.getDescending());

  For M/R, it seems like FlowRuntimeProps.flowRuntimeProps().setGatherPartitions(1) seems to do global ordering.

Thanks,
Ron
