You can see here L208, when we called 'revertPartialWritesAndClose', the written reocrds will decrease to 0. |

…er.commitAndGet called ## What changes were proposed in this pull request? 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. ## How was this patch tested? Modified existing test. Please review http://spark.apache.org/contributing.html before opening a pull request. Author: Xianyang Liu <[email protected]> Closes #18830 from ConeyLiu/DiskBlockObjectWriter. (cherry picked from commit 534a063) Signed-off-by: Wenchen Fan <[email protected]>
