Reynold Xin updated SPARK-14619:
--------------------------------
Description:
When there are multiple attempts for a stage, we currently only reset internal
accumulator values if all the tasks are resubmitted. It would make more sense
to reset the accumulator values for each stage attempt. This will allow us to
eventually get rid of the internal flag in the Accumulator class.
> Track internal accumulators (metrics) by stage attempt rather than stage
