> Project: Spark
> Issue Type: Bug

>
> SqlAppStatusListener does
> {code}
> exec.driverAccumUpdates = accumUpdates.toMap
> update(exec)
> {code}
> in onDriverAccumUpdates.
> But postDriverMetricUpdates is called multiple time per query, e.g. from each
> FileSourceScanExec and BroadcastExchangeExec.
> If the update does not really update it in the KV store (depending on
> liveUpdatePeriodNs), the previously posted metrics are lost.
