They can be used to implement counters (as in MapReduce) or sums. Spark natively supports accumulators of numeric types, and programmers can add support for new types. If accumulators are created with a name, they will be -displayed in Spark's UI. This can can be useful for understanding the progress of +displayed in Spark's UI.
