with hive

Inaccurate result while comparing the result of carbon table with hive
Steps to reproduce:
1) Create carbondata table and load data in it:
a) create table Comp_VMALL_DICTIONARY_INCLUDE (imei string,deviceInformationId
int,MAC string,deviceColor string,device_backColor string,modelId
string,marketName string,AMSize string,ROMSize string,CUPAudit
string,CPIClocked string,series string,productionDate timestamp,bomCode
string,internalModels string, deliveryTime string, channelsId string,
channelsName string , deliveryAreaId string, deliveryCountry string,
deliveryProvince string, deliveryCity string,deliveryDistrict string,
deliveryStreet string, oxSingleNumber string, ActiveCheckTime string,
ActiveAreaId string, ActiveCountry string, ActiveProvince string, Activecity
string, ActiveDistrict string, ActiveStreet string, ActiveOperatorId string,
Active_releaseId string, Active_EMUIVersion string, Active_operaSysVersion
string, Active_BacVerNumber string, Active_BacFlashVer string,
Active_webUIVersion string, Active_webUITypeCarrVer
string,Active_webTypeDataVerNumber string, Active_operatorsVersion string,
Active_phonePADPartitionedVersions string, Latest_YEAR int, Latest_MONTH int,
Latest_DAY Decimal(30,10), Latest_HOUR string, Latest_areaId string,
Latest_country string, Latest_province string, Latest_city string,
Latest_district string, Latest_street string, Latest_releaseId string,
Latest_EMUIVersion string, Latest_operaSysVersion string, Latest_BacVerNumber
string, Latest_BacFlashVer string, Latest_webUIVersion string,
Latest_webUITypeCarrVer string, Latest_webTypeDataVerNumber string,
Latest_operatorsVersion string, Latest_phonePADPartitionedVersions string,
Latest_operatorId string, gamePointDescription string,gamePointId
double,contractNumber BigInt) STORED BY 'org.apache.carbondata.format'
TBLPROPERTIES('DICTIONARY_INCLUDE'='imei,deviceInformationId,productionDate,gamePointId,Latest_DAY,contractNumber');
b) LOAD DATA INPATH
'hdfs://hadoop-master:54311/BabuStore/Data/100_olap_C20.csv' INTO table
Comp_VMALL_DICTIONARY_INCLUDE options ('DELIMITER'=',', 'QUOTECHAR'='"',
'BAD_RECORDS_ACTION'='FORCE','FILEHEADER'='imei,deviceInformationId,MAC,deviceColor,device_backColor,modelId,marketName,AMSize,ROMSize,CUPAudit,CPIClocked,series,productionDate,bomCode,internalModels,deliveryTime,channelsId,channelsName,deliveryAreaId,deliveryCountry,deliveryProvince,deliveryCity,deliveryDistrict,deliveryStreet,oxSingleNumber,contractNumber,ActiveCheckTime,ActiveAreaId,ActiveCountry,ActiveProvince,Activecity,ActiveDistrict,ActiveStreet,ActiveOperatorId,Active_releaseId,Active_EMUIVersion,Active_operaSysVersion,Active_BacVerNumber,Active_BacFlashVer,Active_webUIVersion,Active_webUITypeCarrVer,Active_webTypeDataVerNumber,Active_operatorsVersion,Active_phonePADPartitionedVersions,Latest_YEAR,Latest_MONTH,Latest_DAY,Latest_HOUR,Latest_areaId,Latest_country,Latest_province,Latest_city,Latest_district,Latest_street,Latest_releaseId,Latest_EMUIVersion,Latest_operaSysVersion,Latest_BacVerNumber,Latest_BacFlashVer,Latest_webUIVersion,Latest_webUITypeCarrVer,Latest_webTypeDataVerNumber,Latest_operatorsVersion,Latest_phonePADPartitionedVersions,Latest_operatorId,gamePointId,gamePointDescription');
c) repeat the load Query for 5 segments.
2) create Hive tables and load data in it:
a) create table Comp_VMALL_DICTIONARY_INCLUDE_h (imei
string,deviceInformationId int,MAC string,deviceColor string,device_backColor
string,modelId string,marketName string,AMSize string,ROMSize string,CUPAudit
string,CPIClocked string,series string,productionDate timestamp,bomCode
string,internalModels string,deliveryTime string,channelsId string,channelsName
string,deliveryAreaId string,deliveryCountry string,deliveryProvince
string,deliveryCity string,deliveryDistrict string,deliveryStreet
string,oxSingleNumber string,contractNumber BigInt,ActiveCheckTime
string,ActiveAreaId string,ActiveCountry string,ActiveProvince
string,Activecity string,ActiveDistrict string,ActiveStreet
string,ActiveOperatorId string,Active_releaseId string,Active_EMUIVersion
string,Active_operaSysVersion string,Active_BacVerNumber
string,Active_BacFlashVer string,Active_webUIVersion
string,Active_webUITypeCarrVer string,Active_webTypeDataVerNumber
string,Active_operatorsVersion string,Active_phonePADPartitionedVersions
string,Latest_YEAR int,Latest_MONTH int,Latest_DAY Decimal(30,10),Latest_HOUR
string,Latest_areaId string,Latest_country string,Latest_province
string,Latest_city string,Latest_district string,Latest_street
string,Latest_releaseId string,Latest_EMUIVersion string,Latest_operaSysVersion
string,Latest_BacVerNumber string,Latest_BacFlashVer string,Latest_webUIVersion
string,Latest_webUITypeCarrVer string,Latest_webTypeDataVerNumber
string,Latest_operatorsVersion string,Latest_phonePADPartitionedVersions
string,Latest_operatorId string,gamePointId double,gamePointDescription string)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ',';
b) load data local inpath
'/opt/Carbon/CarbonData/TestData/Data/100_olap_C20.csv' INTO TABLE
Comp_VMALL_DICTIONARY_INCLUDE_h;
c) load data local inpath
'/opt/Carbon/CarbonData/TestData/Data/100_olap_C20.csv' INTO TABLE
Comp_VMALL_DICTIONARY_INCLUDE_h;
d) load data local inpath
'/opt/Carbon/CarbonData/TestData/Data/100_olap_C20.csv' INTO TABLE
Comp_VMALL_DICTIONARY_INCLUDE_h;
e) load data local inpath
'/opt/Carbon/CarbonData/TestData/Data/100_olap_C20.csv' INTO TABLE
Comp_VMALL_DICTIONARY_INCLUDE_h;
f) load data local inpath
'/opt/Carbon/CarbonData/TestData/Data/100_olap_C20.csv' INTO TABLE
Comp_VMALL_DICTIONARY_INCLUDE_h;
3) Execute the Queries:
for carbondata:
select max(productionDate),min(productionDate) from
Comp_VMALL_DICTIONARY_INCLUDE;
for Hive:
select max(productionDate),min(productionDate) from
Comp_VMALL_DICTIONARY_INCLUDE_h;
4) Expected Result: As both tables have the same type of data and same no of
rows, the result should be same for both the queries.
5) Actual Result:
Carbondata:
+------------------------+------------------------+--+
| max(productionDate) | min(productionDate) |
+------------------------+------------------------+--+
| 2015-10-07 12:07:28.0 | 2015-07-01 12:07:28.0 |
+------------------------+------------------------+--+
1 row selected (0.717 seconds)
Hive:
+------------------------+------------------------+--+
| max(productionDate) | min(productionDate) |
+------------------------+------------------------+--+
| 2015-10-07 12:07:28.0 | 2015-07-01 08:37:28.0 |
+------------------------+------------------------+--+
1 row selected (0.208 seconds)
