   hello  ask a question：
   1、I create sparksession 
   SparkSession sparkSession = SparkSession.builder().enableHiveSupport().appName("HudiTest")
   .config("spark.serializer","org.apache.spark.serializer.KryoSerializer")
   .getOrCreate();
   2.Configure hudi parameters
   optionMap.put(DataSourceWriteOptions.RECORDKEY_FIELD().key(),"uuid");
   optionMap.put(DataSourceWriteOptions.PRECOMBINE_FIELD().key(),"dt");
   optionMap.put(DataSourceWriteOptions.PARTITIONPATH_FIELD().key(),"dt");
   optionMap.put("hoodie.insert.shuffle.parallelism","10");
   optionMap.put("hoodie.upsert.shuffle.parallelism","10");
   optionMap.put("hoodie.datasource.write.operation","insert");
   optionMap.put("hoodie.parquet.small.file.limit","94857600");
   optionMap.put("hoodie.parquet.max.file.size","200829120");
   optionMap.put("hoodie.merge.allow.duplicate.on.inserts","true");
   optionMap.put(HoodieWriteConfig.TBL_NAME.key(),"my_table_B");
   3.Output Data To Hdfs
   4.**Found small files not merged**
   
   Can you help me to see if the configuration is missing?
