   **Describe the problem you faced**
   
   When we added column `new_col` to middle of existed schema, and sync it to 
hive 
   We got error below
   
   ```
   0/05/14 10:40:45 ERROR HiveSyncTool: Got runtime exception when hive syncing

   ```
   
   A clear and concise description of the problem.
   
   **To Reproduce**
   
   Steps to reproduce the behavior:
   
   1. Setting hudi by using hive options
   ```
         TABLE_NAME -> "table",
         PRECOMBINE_FIELD_OPT_KEY -> "__daas_internal_ts",
         RECORDKEY_FIELD_OPT_KEY -> "id",
         PARTITIONPATH_FIELD_OPT_KEY -> "_partition_key",
         TABLE_TYPE_OPT_KEY -> MOR_TABLE_TYPE_OPT_VAL,
         HIVE_SYNC_ENABLED_OPT_KEY -> "true", 
         HIVE_DATABASE_OPT_KEY -> "XXXX", 
         HIVE_TABLE_OPT_KEY -> "YYYYY",
         HIVE_PARTITION_FIELDS_OPT_KEY -> "created_at",
         HIVE_PARTITION_EXTRACTOR_CLASS_OPT_KEY -> 
classOf[MultiPartKeysValueExtractor].getName
   ```
   2. Create a DF with column and write to hudi tables
   3. Create a same DF2 as 2. with a new column in middle
   4. Write DF2 to hudi table
   
   **Expected behavior**
   Same exception as description 
   
   A clear and concise description of what you expected to happen.
   I think there are already detected the schema changement

   Should also support update hive schema for each pattern
   
   **Environment Description**
   
   * Hudi version : 0.5.2
   
   * Spark version : 2.4.4
   
   * Hive version : 3.1.2
   
   * Hadoop version : 3.1.2
