tanghui updated HIVE-26158:
---------------------------
Summary: TRANSLATED_TO_EXTERNAL partition tables cannot query partition
data after rename table (was: TRANSLATED_TO_EXTERNAL partition tables cannot
query partition data after rename)
> TRANSLATED_TO_EXTERNAL partition tables cannot query partition data after
> rename table
> --------------------------------------------------------------------------------------
>
> Key: HIVE-26158
> URL: https://issues.apache.org/jira/browse/HIVE-26158
> Project: Hive
> Issue Type: Bug
> Affects Versions: 4.0.0, 4.0.0-alpha-1, 4.0.0-alpha-2
> Reporter: tanghui
> Priority: Major
>
> After the patch is updated, the partition table location and hdfs data
> directory are displayed normally, but the partition location of the table in
> the SDS in the Hive metabase is still displayed as the location of the old
> table, resulting in no data in the query partition.
> ------------------------------------------------------------
> set hive.create.as.external.legacy=true;
> CREATE TABLE part_test(
> c1 string
> ,c2 string
> )PARTITIONED BY (dat string)
> insert into part_test values ("11","th","20220101")
> insert into part_test values ("22","th","20220102")
> alter table part_test rename to part_test11;
> --this resulting in no data in the query partition.
> select * from part_test11 where dat="20220101";
> ---------------------------------------------------------------------------------------------
> SDS in the Hive metabase:
> select SDS.LOCATION from TBLS,SDS where TBLS.TBL_NAME="part_test11" AND
> TBLS.TBL_ID=SDS.CD_ID;
> ---------------------------------------------------------------------------------------------------
> |LOCATION|
> |hdfs://nameservice1/warehouse/tablespace/external/hive/part_test11|
> |hdfs://nameservice1/warehouse/tablespace/external/hive/part_test/dat=20220101|
> |hdfs://nameservice1/warehouse/tablespace/external/hive/part_test/dat=20220102|
> ---------------------------------------------------------------------------------------------------
>
> We need to modify the partition location of the table in SDS to ensure that
> the query results are normal
