> when finish the sixth operation where two records inserted and `compaction` in `TestMORDataSource.testCount`,  `hudiIncDF6.count()` returns 152. Because there are 150 records which just have finished the `compaction` and consist of 100 records updated in the second and  third times and 50 records updated in the fifth updated, and 2 records inserted in the six time.
> The right answer should be 2, and 150 records should not be counted in.
> The reason is that `compaction` has changed the commit time of some records which are updated later and stored in log file. 
> {code:java}
> val hudiIncDF6 = spark.read.format("org.apache.hudi")
>   .option(DataSourceReadOptions.QUERY_TYPE.key, DataSourceReadOptions.QUERY_TYPE_INCREMENTAL_OPT_VAL)
>   .option(DataSourceReadOptions.BEGIN_INSTANTTIME.key, commit5Time)
>   .option(DataSourceReadOptions.END_INSTANTTIME.key, commit6Time)
>   .load(basePath)
> // compaction updated 150 rows + inserted 2 new row
> assertEquals(152, hudiIncDF6.count()) {code}
