Review Comment:
   thanks for your comment. 
   
   ValidationUils is a good suggestion, already done. 
   
   But because the property: HIVE_BATCH_SYNC_PARTITION_NUM is an optional 
param, if the user does not set it, then we will use the default value, then 
the sync config level(HiveSyncConfig.java) might not fit.
