   @qingyuan18  InputFormat and outputFormat for this table 
`xxxx.xxxx_acidtest2` does not seem to be Hudi related.  The SerDe formats for 
MOR tables look like :
   
   for read optimized MOR table
   | # Storage Information         | NULL                                       
                     | NULL                  |
   | SerDe Library:                | 
org.apache.hadoop.hive.ql.io.parquet.serde.ParquetHiveSerDe     | NULL          
        |
   | InputFormat:                  | 
org.apache.hudi.hadoop.HoodieParquetInputFormat                 | NULL          
        |
   | OutputFormat:                 | 
org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat  | NULL          
        |
   
   and for _rt suffixed MOR table
   
   | # Storage Information         | NULL                                       
                       | NULL                  |
   | SerDe Library:                | 
org.apache.hadoop.hive.ql.io.parquet.serde.ParquetHiveSerDe       | NULL        
          |
   | InputFormat:                  | 
org.apache.hudi.hadoop.realtime.HoodieParquetRealtimeInputFormat  | NULL        
          |
   | OutputFormat:                 | 
org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat    | NULL        
          |
