      Description

      We don't use that in parallelism estimation and only use that in ShuffleVertexManager. Usually it is fine, but in cases when user has set a really low bytes.per.reducer it does not work as our estimation is low. ShuffleVertexManager only decreases parallelism and not increases parallelism.
