> Reporter: Amit Sela
> Assignee: Aviem Zur

> While Aggregators are fault-tolerant (pending https://github.com/apache/incubator-beam/pull/909), they will recover into their initial value.
> The SparkRunner should persist the values to durable storage and recover from the persisted state.
> One way to go would be to persist via Spark's listeners, for example "onBatchCompleted".
> For more details see SPARK-5206.
