>                 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. Execution engine set to MapReduce
> 2. Partition columns have different types
> 3. Both static and dynamic partitions are used in the query
> 4. 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;
> set hive.execution.engine=mr;
> 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__
