…6732) Problem Summary: before pr : apache#44038 In the previous PR, the generation method of split in the count( * ) scenario was optimized. However, there were some problems with the hive acid table. This PR mainly fixes this and adds tests. In the count( * ) scenario, reading the hive full acid table cannot be optimized, and the file still needs to be split (merge on read is required), and the hive insert only acid table does not need to be split.
