                 Key: CARBONDATA-2225
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-2225

Inaccurate result displays while using histogram_numeric

Steps to reproduce:

1: Create carbon table:

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://localhost:54310/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://localhost:54310/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://localhost:54310/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://localhost:54310/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://localhost:54310/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:

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 '/home/knoldus/Desktop/csv/TestData/Data/uniqdata/2000_UniqData.csv' into table uniqdata_h;

c) load data local inpath '/home/knoldus/Desktop/csv/TestData/Data/uniqdata/4000_UniqData.csv' into table uniqdata_h;

d) load data local inpath '/home/knoldus/Desktop/csv/TestData/Data/uniqdata/6000_UniqData.csv' into table uniqdata_h;

e) load data local inpath '/home/knoldus/Desktop/csv/TestData/Data/uniqdata/7000_UniqData.csv' into table uniqdata_h;

f)load data local inpath '/home/knoldus/Desktop/csv/TestData/Data/uniqdata/3000_1_UniqData.csv' into table uniqdata_h;

3) Execute Query:

a) hive:

select histogram_numeric(1,2) 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 ;

output:

+------------------------------------------------+--+
| histogram_numeric( 1, 2) |
+------------------------------------------------+--+
| [\{"x":1.0,"y":12040.0},\{"x":1.0,"y":10026.0}] |
+------------------------------------------------+--+
1 row selected (3.173 seconds)

 

b) Carbon:

select histogram_numeric(1,2) 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 ;

output:

+-----------------------------------------------+--+
| histogram_numeric( 1, 2) |
+-----------------------------------------------+--+
| [\{"x":1.0,"y":13039.0},\{"x":1.0,"y":9027.0}] |
+-----------------------------------------------+--+
1 row selected (0.95 seconds)

 

4) Expected Result: Result of spark hive and carbon should be same for the same function with same data.
