----------------------------------------
Summary: Incorrect result displays while using not equal to (!=) operator in presto integration
Key: CARBONDATA-983
URL:
https://issues.apache.org/jira/browse/CARBONDATA-983 Project: CarbonData
Issue Type: Bug
Components: data-query, presto-integration
Affects Versions: 1.1.0
Environment: spark 2.1, presto 0.166
Reporter: Vandana Yadav
Priority: Minor
Attachments: 2000_UniqData.csv
Incorrect result displays while using not equal to (!=) operator in presto integration(result set should exclude the provided record but it is present in our result set)
Steps to reproduce :
1. In CarbonData:
a) Create table:
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 :
LOAD DATA INPATH 'hdfs://localhost:54310/2000_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');
2. In presto
a) Execute the query:
DECIMAL_COLUMN1 from UNIQDATA where DECIMAL_COLUMN1 !=12345678902.1234000000 order by DECIMAL_COLUMN1;
b) Actual Result:
In Carbondata:
+-------------------------+--+
| DECIMAL_COLUMN1 |
+-------------------------+--+
| 12345678901.1234000000 |
| 12345678901.1234000000 |
| 12345678903.1234000000 |
| 12345678904.1234000000 |
| 12345678905.1234000000 |
In presto:
DECIMAL_COLUMN1
------------------------
12345678901.1234000000
12345678901.1234000000
12345678902.1234000000
12345678903.1234000000
12345678904.1234000000
