------------------------------
Summary: TRANSLATED_TO_EXTERNAL partition tables cannot query
partition data after rename
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
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
