---------------------------
Assignee: (was: Amit Sela)
> Persist and restore Aggergator values in case of recovery from failure
> ----------------------------------------------------------------------
>
> Key: BEAM-648
> URL: https://issues.apache.org/jira/browse/BEAM-648
> Project: Beam
> Issue Type: Bug
> Components: runner-spark
> Reporter: Amit Sela
>
> 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.
