INSERT OVERWRITE DIRECTORY '/opt/elk_shell/ec_temp_base_real_add_result/' ROW FORMAT DELIMITED FIELDS TERMINATED BY '&' select * from hive_web.ec_temp_base_real_add_result where processtime >= '$ti_yestday_format'

这是一个Hive SQL查询语句,用于将查询结果覆盖写入到指定目录中的文件中。
该查询语句的含义是从名为 `hive_web.ec_temp_base_real_add_result` 的表中选择所有满足 `processtime` 大于等于 `$ti_yestday_format` 的记录,并将查询结果以 `&` 作为字段分隔符的形式写入到 `/opt/elk_shell/ec_temp_base_real_add_result/` 目录中。
请确保目录 `/opt/elk_shell/ec_temp_base_real_add_result/` 存在且可写,并且表 `hive_web.ec_temp_base_real_add_result` 中有符合条件的数据。同时,确保 `$ti_yestday_format` 变量的值在查询之前已经正确设置。
注意,在执行该查询之前,你需要在 Hive CLI 或 Hive Beeline 中连接到 Hive 数据库,并确保具有足够的权限来执行该查询。

cp: cannot overwrite non-directory 'obj/kernel/liteos_a/apps/toybox/toybox_build/toybox' with directory '../../../third_party/toybox'
This error occurs because you are trying to copy a directory (../../../third_party/toybox) over a file (obj/kernel/liteos_a/apps/toybox/toybox_build/toybox).
To fix this error, you should remove the existing file first using the command:
```
rm obj/kernel/liteos_a/apps/toybox/toybox_build/toybox
```
Then, you can copy the directory over using the command:
```
cp -r ../../../third_party/toybox obj/kernel/liteos_a/apps/toybox/toybox_build/toybox
```
The -r option tells the cp command to copy the directory and its contents recursively.
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:
```sql
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。
