Subject [jira] [Created] (CARBONDATA-983) Incorrect result displays while using not equal to (!=) operator in presto integration
Date Tue, 25 Apr 2017 06:50:04 GMT
Vandana Yadav created CARBONDATA-983:
----------------------------------------

             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
