i created a hive external table, when i exeute this hive sql----alter table
log_nlp_industory_log add partition (dt='${biz_date}') location
'/log/nlp/${biz_date}', the replace sql is print----alter table
log_nlp_industory_log add partition (dt=?) location '/log/nlp/?
obvious， this replace sql is not conform to hive's grammar
