检查一下是否存在语法错误insert overwrite local directory '/home/map/chenlinyu/task2' row format delimited fields terminated by '\t' SELECT t2.city_name, COUNT(*) as count FROM map_huiyan_short_stay t1 JOIN map_huiyan_long_stay_with_area t2 ON t1.cuid = t2.cuid WHERE t2.event_day=20230605 and t1.loc_x>12993523 and t1.loc_x<13012467 and t1.loc_y>4773079 and t1.loc_y<4789463 group by t2.city_name

这段代码存在一些语法错误。在使用INSERT OVERWRITE语句时，需要指定目标表，而你的代码中没有指定目标表。此外，你还需要使用INSERT语句来将查询结果插入到指定的目录中。

以下是修正后的代码：

INSERT OVERWRITE DIRECTORY '/home/map/chenlinyu/task2'
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '\t'
SELECT t2.city_name, COUNT(*) AS count
FROM map_huiyan_short_stay t1
JOIN map_huiyan_long_stay_with_area t2 ON t1.cuid = t2.cuid
WHERE t2.event_day = 20230605
  AND t1.loc_x > 12993523
  AND t1.loc_x < 13012467
  AND t1.loc_y > 4773079
  AND t1.loc_y < 4789463
GROUP BY t2.city_name;

请确保将目标表替换为你想要插入数据的实际目录，并执行修正后的代码。
