> SQLHistoryListener listens on SparkListenerTaskEnd events, which contain non-SQL accumulators as well. We try to cast all accumulators we encounter to Long, resulting in an error like this one.
> Note: this was a problem even before internal accumulators were introduced. If  the task used a user accumulator of a type other than Long, we would still see this.
