------------------------------------
Summary: Merge of dynamic partitions loads all data to default
partition
Key: HIVE-10980
URL: https://issues.apache.org/jira/browse/HIVE-10980
Project: Hive
Issue Type: Bug
Components: Hive
Affects Versions: 0.14.0
Environment: HDP 2.2.4 (also reproduced on apache hive built from
trunk)
Reporter: Illya Yalovyy
Conditions that lead to the issue:
1. Partition columns have different types
2. Both static and dynamic partitions are used in the query
3. Dynamically generated partitions require merge
Result: Final data is loaded to "__HIVE_DEFAULT_PARTITION__".
Steps to reproduce:
set hive.exec.dynamic.partition=true;
set hive.exec.dynamic.partition.mode=strict;
set hive.optimize.sort.dynamic.partition=false;
set hive.merge.mapfiles=true;
set hive.merge.mapredfiles=true;
set hive.input.format=org.apache.hadoop.hive.ql.io.HiveInputFormat;
create external table sdp (
dataint bigint,
hour int,
req string,
cid string,
caid string
)
row format delimited
fields terminated by ',';
load data local inpath '../../data/files/dynpartdata1.txt' into table sdp;
load data local inpath '../../data/files/dynpartdata2.txt' into table sdp;
...
load data local inpath '../../data/files/dynpartdataN.txt' into table sdp;
create table tdp (cid string, caid string)
partitioned by (dataint bigint, hour int, req string);
insert overwrite table tdp partition (dataint=20150316, hour=16, req)
select cid, caid, req from sdp where dataint=20150316 and hour=16;
select * from tdp order by caid;
show partitions tdp;
Example of the input file:
20150316,16,reqA,clusterIdA,cacheId1
20150316,16,reqB,clusterIdB,cacheId2
20150316,16,reqA,clusterIdC,cacheId3
20150316,16,reqD,clusterIdD,cacheId4
20150316,16,reqA,clusterIdA,cacheId5
Actual result:
clusterIdA cacheId1 20150316 16
__HIVE_DEFAULT_PARTITION__
clusterIdA cacheId1 20150316 16
__HIVE_DEFAULT_PARTITION__
clusterIdB cacheId2 20150316 16
__HIVE_DEFAULT_PARTITION__
clusterIdC cacheId3 20150316 16
__HIVE_DEFAULT_PARTITION__
clusterIdD cacheId4 20150316 16
__HIVE_DEFAULT_PARTITION__
clusterIdA cacheId5 20150316 16
__HIVE_DEFAULT_PARTITION__
clusterIdD cacheId8 20150316 16
__HIVE_DEFAULT_PARTITION__
clusterIdB cacheId9 20150316 16
__HIVE_DEFAULT_PARTITION__
dataint=20150316/hour=16/req=__HIVE_DEFAULT_PARTITION__
