>
> Currently all the partitioner vertex and final reducer vertex tasks are
> started as soon as the sampler vertex completes. The final reducer vertex
> tasks should only start after a percentage of partitioner vertex tasks have
> completed. We need to do same kind of slow start as ShuffleVertexManager
> honoring ShuffleVertexManager.TEZ_SHUFFLE_VERTEX_MANAGER_MIN_SRC_FRACTION and
> ShuffleVertexManager.TEZ_SHUFFLE_VERTEX_MANAGER_MAX_SRC_FRACTION
> configurations and their defaults.
