             Summary: Reset numRecordsWritten after DiskBlockObjectWriter.commitAndGet called
                 Key: SPARK-21621
                 URL: https://issues.apache.org/jira/browse/SPARK-21621
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 2.2.0
            Reporter: Xianyang Liu


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.
