Summary: Comparison failure while applying datediff(DOB,DOJ) on
carbon and hive table
Key: CARBONDATA-2678
URL: https://issues.apache.org/jira/browse/CARBONDATA-2678
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
Comparison failure while applying datediff(DOB,DOJ) on carbon and hive table:
Steps to reproduce:
1) Create carbon table 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_URL/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_URL/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_URL/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_URL/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 Hive table 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
load data local inpath
'/opt/Carbon/CarbonData/TestData/Data/uniqdata/4000_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 Query :
Carbon table:
select datediff(DOB,DOJ) from uniqdata where CUST_ID IS NULL or DOB IS NOT NULL
or BIGINT_COLUMN1 =1233720368578 or DECIMAL_COLUMN1 = 12345678901.1234000058 or
Double_COLUMN1 = 1.12345674897976E10 or INTEGER_COLUMN1 IS NULL order by DOB
Hive table:
select datediff(DOB,DOJ) from uniqdata_h where CUST_ID IS NULL or DOB IS NOT
NULL or BIGINT_COLUMN1 =1233720368578 or DECIMAL_COLUMN1 =
12345678901.1234000058 or Double_COLUMN1 = 1.12345674897976E10 or
INTEGER_COLUMN1 IS NULL order by DOB
4) Expected result:
the result of both the queries should be same as both the tables as the similar
data set.
5) Actual Result:
there is a difference of null values in carbondata as compare to hive:
