As a person, you'll be able to create named or unnamed accumulators.

All transformations in Spark are lazy, in that they don't compute their success right away. As an alternative, They only bear in mind the transformations applied to some base dataset (e.g. a file). The transformations are only computed when an action demands a outcome being returned to the motive force program.
