-----------------------------------------

             Summary: Incorrect results set for the same query in hive and carbondata
                 Key: CARBONDATA-2663
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-2663
             Project: CarbonData
          Issue Type: Bug
          Components: data-query
    Affects Versions: 1.5.0
         Environment: spark 2.2
            Reporter: Vandana Yadav
         Attachments: 2000_UniqData.csv, 3000_1_UniqData.csv, 4000_UniqData.csv, 6000_UniqData.csv, 7000_UniqData.csv

Incorrect results set for the same query in hive and carbondata:

Steps to reproduce:

1) Create a table in carbondata and load data in it.

a) CREATE TABLE uniqdata (CUST_ID int,CUST_NAME String,ACTIVE_EMUI_VERSION string, DOB timestamp, DOJ timestamp, BIGINT_COLUMN1 bigint,BIGINT_COLUMN2 bigint,DECIMAL_COLUMN1 decimal(30,10), DECIMAL_COLUMN2 decimal(36,10),Double_COLUMN1 double, Double_COLUMN2 double,INTEGER_COLUMN1 int) STORED BY 'org.apache.carbondata.format' TBLPROPERTIES ("TABLE_BLOCKSIZE"= "256 MB")

b) LOAD DATA INPATH 'HDFS_URL/BabuStore/Data/uniqdata/2000_UniqData.csv' into table uniqdata OPTIONS('DELIMITER'=',' , 'QUOTECHAR'='"','BAD_RECORDS_ACTION'='FORCE','FILEHEADER'='CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1')

c) LOAD DATA INPATH 'hdfs://hadoop-master:54311/BabuStore/Data/uniqdata/4000_UniqData.csv' into table uniqdata OPTIONS('DELIMITER'=',' , 'QUOTECHAR'='"','BAD_RECORDS_ACTION'='FORCE','FILEHEADER'='CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1')

d) LOAD DATA INPATH 'hdfs://hadoop-master:54311/BabuStore/Data/uniqdata/6000_UniqData.csv' into table uniqdata OPTIONS('DELIMITER'=',' , 'QUOTECHAR'='"','BAD_RECORDS_ACTION'='FORCE','FILEHEADER'='CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1')

e) LOAD DATA INPATH 'hdfs://hadoop-master:54311/BabuStore/Data/uniqdata/7000_UniqData.csv' into table uniqdata OPTIONS('DELIMITER'=',' , 'QUOTECHAR'='"','BAD_RECORDS_ACTION'='FORCE','FILEHEADER'='CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1')

f) LOAD DATA INPATH 'hdfs://hadoop-master:54311/BabuStore/Data/uniqdata/3000_1_UniqData.csv' into table uniqdata OPTIONS('DELIMITER'=',' , 'QUOTECHAR'='"','BAD_RECORDS_ACTION'='FORCE','FILEHEADER'='CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1')

 

2) create a table with hive and load data in it:

a) CREATE TABLE uniqdata_h (CUST_ID int,CUST_NAME String,ACTIVE_EMUI_VERSION string, DOB timestamp, DOJ timestamp, BIGINT_COLUMN1 bigint,BIGINT_COLUMN2 bigint,DECIMAL_COLUMN1 decimal(30,10), DECIMAL_COLUMN2 decimal(36,10),Double_COLUMN1 double, Double_COLUMN2 double,INTEGER_COLUMN1 int) ROW FORMAT DELIMITED FIELDS TERMINATED BY ','

b) load data local inpath '/opt/Carbon/CarbonData/TestData/Data/uniqdata/2000_UniqData.csv' into table uniqdata_h

c) load data local inpath '/opt/Carbon/CarbonData/TestData/Data/uniqdata/4000_UniqData.csv' into table uniqdata_h

d) load data local inpath '/opt/Carbon/CarbonData/TestData/Data/uniqdata/6000_UniqData.csv' into table uniqdata_h

e) load data local inpath '/opt/Carbon/CarbonData/TestData/Data/uniqdata/7000_UniqData.csv' into table uniqdata_h

f) load data local inpath '/opt/Carbon/CarbonData/TestData/Data/uniqdata/3000_1_UniqData.csv' into table uniqdata_h

 

3) Execute the desired Query:

a) Carbondata:

select DOB from UNIQDATA where DOB != DOJ order by DOB

b) Hive:

select DOB from uniqdata_h where DOB != DOJ order by DOB

 

4) Expected Result: result set for both hive and carbondata should be same as we are fetching data from the same dataset.

5) Actual Result:

a) Carbondata:
