> Project: Spark
> Issue Type: Bug
> Components: Spark Core

>
> We should reset numRecordsWritten to zero after
> DiskBlockObjectWriter.commitAndGet called.
> Because when `revertPartialWritesAndClose` be called, we decrease the
> written records in `ShuffleWriteMetrics` . However, we decreased the written
> records to zero, this should be wrong, we should only decreased the number
> reords after the last `commitAndGet` called.
