必须删除2023-03-26至2023-07-10的重复数据。我尝试使用此命令从表中删除重复项,但出现错误。
命令:
set hive.exec.dynamic.partition.mode=nonstrict; INSERT OVERWRITE TABLE db.table_name PARTITION(dt) select distinct * from db.table_name where dt >= '2023-03-26' AND dt >= '2023-07-10';

错误代码:
23/07/26 16:07:46 [LocalJobRunner Map Task Executor #0]: WARN io.CombineHiveRecordReader: Multiple partitions found; not going to pass a part spec to LLAP IO: {{dt=2023-07-10}} and {{dt=2023-07-11}} 2023- 07-26 16:07:47,952 Stage-1 map = 0%, reduce = 0% 23/07/26 16:07:47 [aabca681-0714-44f6-bc8d-9be6d7fca9fc main]: WARN mapreduce.Counters: Group org.apache.hadoop.mapred.Task$Counter is deprecated. Use org.apache.hadoop.mapreduce.TaskCounter instead.

注意:此表的分区仅为日期。示例如下:
show partitions db.table_name;
dt=2023-07-04
dt=2023-07-05
dt=2023-07-06
dt=2023-07-07
dt=2023-07-08
dt=2023-07-09
dt=2023-07-10
$ hive --version
Hive 2.3.3
的字符串
希望你能在这一点上提出建议。谢谢你,谢谢
